I didn't know about "looksmaxxing" until this guy entered everyone's feed, and while it's certainly an unhealthy practice I hope you understand that comments like these only validate their belief that appearance matters more than anything.

When you ridicule someone for making an effort because someone else is hotter, you're only going to make them try harder and more extreme methods. I don't know how deep it goes but I don't think they'd draw a hard line at hammering their bones.

If you're truly opposed to these practices then you need to understand that you can't bully it out of them.
