Yes, there's alarming content on TikTok. Guess what? There's a LOT of that on YouTube & Twitter too. Your problem should be with society, not TikTok.
(Here, I'm talking about the stuff that's *not* inappropriate)
First the privileged use it, that's what makes it 'cool'.
Then the middle class uses it, that's what makes it 'massy'.
But when it is finally accessible to the lesser privileged sections of society, it becomes 'cringe'.
Because we CANNOT gate-keep who gets to create and who gets to express.
When we judge the young people on TikTok, we need to judge the society that conditions them.
REGULATE the platform. And while at it, regulate ALL PLATFORMS. Because hate exists on all, except that on some it wears more expensive clothes.
But that requires hard work.
The easy way: Let's look away, and ban TikTok?
Sigh.
