In US, it might take the form of veganism - a revolt against the mainstream "steakhouse" culture
In India, it takes the form of "beef parties" - a cultural revolt against the austerity of the H-masses
But the same liberals would no doubt rebel against "brahminism" if you were to place them in India
This wasnt always the case. At one point liberalism was about standing up for mass culture against the hegemony of high culture in any society
Modern liberalism is about standing up for the people who don't fit in. Standing up for their identities. Their cultural choices.
That could be a Hare Krishna devotee in US. It might be an evangelical Christian in India
Most notably it features in the writings of John Stuart Mill who wrote his great book "On Liberty" in mid 19th century
This is very different from the Liberalism of the "Progressive"leftists for whom liberty mattered less, and equality mattered more
In the first half of 20th cen, the brand of liberalism that enjoyed success was the Rooseveltian version - the liberalism that focused on redistribution, equality
The liberalism that Mill talked about - his worries about the "tyranny of the majority" and the repression of the individual - was not that prominent
The Great Depression and the two great wars ensured that culture wars were not on anybody's mind
And this focus contiued after the War. As evidenced by Johnson's Great Society program in the 60s
FIrst of all, economic prosperity was now not the preserve of few, but had deeply percolated society (atleast in the West). So the liberal attention gradually shifted from the economic to the cultural sphere
The Rooseveltian / Keynesian liberalism was now passe. Liberalism v2.0 was about fighting culture wars, and defending individual cultural choices against those of the masses
Much of it is about "culture wars" - defending the unorthodox. Defending people who buck the trend around them.
The gradual shift from old fashioned progressive politics (inspired by people like Henry George / Karl Marx in 19th cen) to the more individual-centric liberalism of John Stuart Mill.
A radical shift that has gone unnoticed
