Not eating beef is not only religious for Hindus but it also has some historical-political context. As @Infinitchy says it is a symbol of H resistance.
In medieval India, cow slaughter was rampantly used as a symbol of Hindu subjugation by Invaders.
Here are some instances:
1. Firuz Shah Tughlaq broke the idols and mixing the fragments with pieces of cow’s flesh, filled bags with them, and caused them to be tied around the necks of Brahmins who were then paraded through the camp
(Tarikh-i-Firishta)
2. In the reign of Akbar near Nagarkot in an idol temple nearly 200 black cows were killed and then Turks took off their boots and filled them with the blood and cast it up on the roof and walls of the temple. (Tabqat-i-Akbari )
3. Siyar al-Aqtab records “there was 1 temple to reverence which d Raja &all d infidels used to come..when d Khwaja [Mu’in al-Din Chishti of Ajmer, on whose dargah H go to offer chadar] settled there, every day his servants bought a cow, brought it there &slaughtered it &ate it.”
4. Akhbarat records: “The Emperor (Aurangzeb).. ordered..to demolish the temple of Pandharpur..and slaughter cows in the temple. It was done.”
5. Ãsaru’l-Bilad records “Muhammad Qasim.. attached a piece of cow’s flesh to its (idol’s) neck.”
6. Ahmad Shah Durr-i-Durran in 1762 blew up the Harimandir at Amritsar, filled up the sacred tank with the debris, and desecrated the holy site by slaughtering cows on it.
Reproducing some of the writings/speech by this Stalinist known as an 'eminent historian':
1. Lord Indra is 'rowdy & amoral'. 2. The god Krishna has a 'rather questionable personal record'. 3. Lord Shiva is just 'a development of phallic cults'.
4. Bhakti is just the reflection of the complete dependence of the serfs or tenants on the landowners in the context of Indian feudal society. 5. Another myth which, through repetition has been made to stick to the artifact called Hinduism is that it is a tolerant religion.
6. Hinduism is d youngest of all religions, a 19th-century neologism popularized by d British. 7. Nor did any sanatandharma exists,it had to wait for its first codification by d Englishwoman, Annie Besant who,in collaboration with..Bhagwan Das drew up a textbook on sanatandharma.
In Jan1670, Krishna Janmsthan Temple was destroyed on orders of Aurangzeb.
The contemporary account Ma’sir-i-‘Ãlamgiri records:
"On 27th January: During this month of Ramzan..d reviver of the faith of the Prophet issued orders for d demolition of d temple situated in Mathura..
..famous as the Dehra of Kesho Rai. In a short time by the great exertions of his officers the destruction of this strong foundation of infidelity was accomplished, and on its site a lofty mosque was built.. (2/4)
..Praised be the august God of the faith of !zl@m, that in the auspicious reign of this destroyer of infidelity and turbulence, such a wonderful and seemingly impossible work was successfully accomplished... (3/4)
The 'greatest Hindu' blamed Hindus for the Moplah genocide of Hindus. Gandhi said:
"Hindus must find out the causes of Moplah fanaticism. They will find that they are not without blame...it is no use now becoming angry with the Moplahs or the Muzulmans in general." 26th Jan 1922
After the Moplah genocide of Hindus, the 'greatest Hindu' asked Hindus to love Moplahs more. Gandhi said:
"..Even so is it more necessary for a Hindu to love the Moplah and the Muzulman more when the latter is likely to injure him or has already injured him" 26th Jan 1922
The 'greatest Hindu' whitewashed the Moplah genocide of Hindus by calling it a revolt and felt that it came as a blessing. Gandhi said:
"I feel the Moplah revolt has come as a blessing to a system that is crumbling to pieces by the weight of its own enormity" 20th Oct 1921
"He [Gandhi] has no reason in him at all, never was reasonable at any moment in his life & I suppose never will be..I don't think he is himself really sure what he will do next.He has not only 2 minds but 3 or 4 minds."

"Gandhi is a European- truly a Russian Christain in an Indian body...What he preaches is not Indian spirituality but something derived from Russian Christianity, non-violence, suffering, etc" - Sri Aurobindo on 22nd June 1926
"All his [Gandhi] preaching is derived from Christianity and though the garb is Indian the essential spirit is Christian. He may not be Christ, but at any rate, he comes in continuation of the same impulsion." - Sri Aurobindo on 22nd June 1926
Today is d birth anniversary of d veteran historian R. C. Majumdar who refused to bend history to suit the interest of secularists & presented Izl@mic imperialism in medieval India as it was & not as Stalinist & Muzlim historians & d politicians were tailoring it to become. (1/n)
For him, this “national integration” based on willful blindness to the recorded history of the havoc wrought by Izl@m in India, could lead only to national suicide. (2/n)
He writes: "Unfortunately, slogans and beliefs die hard and many Indians especially Hindus are peculiarly sensitive to any comments or observations touching upon the communal relation in any way. (3/n)
“With the grace of Prophet Mohammed and Allah, almost all Hindus in Calicut are converted to Islam. Only on the borders of Cochin State a few are still not converted. I am determined to convert them also very soon. I consider this as Jehad to achieve that object.” - Tipu Sultan..
“Don’t you know I have achieved a great victory recently in Malabar and over four lakh Hindus were converted to Islam? I am determined to march against that cursed ‘Raman Nair’ very soon (referring to the king of Travancore)..
..Since I am overjoyed at the prospect of converting him and his subjects to Islam, I have happily abandoned the idea of going back to Srirangapatanam now." - Tipu in his letter to Budruz Zuman Khan. #TipuSultan
