It's not okay to mock fat women but somehow it's socially acceptable to make fun of bald men?
Bald men are discriminated against for jobs and are often joked about but it's not like they can control their genetics. Fat people can actually lose the weight.
I have noticed a lot of men in their teens and 20s are balding these days and no one is standing up for them.
The bad guys in movies and media are almost always bald.
Larry David, is that you? For a moment i thought this was a bit from Curb your enthusiasm.

Baldness also often signals authority.
In where i live, it isn't ok to joke about bald young people, but then again it isn't ok to joke about anything related to physical appearance, yet people keep doing that. Especially teens can be very insensitive and rough toward each other. Only thing you can do is be an example
When i started balding i was first a little ashamed, but after a while i embraced it, and because of it, i got ton of confidence. Way more then those that would laugh to bald people, and because of it, i got way more done too.
