You're correct that one can lose weight - only most don't because it's so difficult. Not for lack of trying.

I'm just so sick and tired of all these people moaning about how badly people are treating them - it's antisemitism, it's trans, it's obesity, it's been black. WTF?

My point is that everybody is always disliked and badly treated by someone somewhere. About the only people who don't get it in the neck all the time are a particular sort of white male born to privilege. That's it.
