My hot take is, social media alongside with TikTok showed the world to some people who usually wouldn’t venture out of their small bubbles. Eventually they see significant positive things about other countries, and a lot of negative about theirs. This subconsciously brings up “we have it worse for sure!” emotions in some people, that later translated into whatever it is right now when some people started targeting and exploiting these feelings.

I have no source, no data, nor examples to defend my point, it’s just the vibes.
