Is it normal that I think fat people don't have feelings?

"You be the judge," you say? Okay, I'll judge.

You're shallow, vain and stupid enough to mistreat other people, and you think your targets are the ones who will suffer in this life? Fat people can lose weight, although they don't do it because of the shaming they get from little high school girls, but you'll peak right where you are. The best you'll ever achieve is what you are right now because you've tied your self-worth to your waist size and not other, more meaningful things like kindness, empathy, intelligence or education (yeah, that shows in your writing, in case you were wondering how I spotted that).

They walk away because they know they're better than you. Someday, they'll lose weight -- or not, because size isn't really attached to self-worth for some people the way it is to you -- but you'll always be stuck where you are. They'll mature, develop careers, grow as people; you'll still be the mean girl at the cool kids' table, but who wants to sit at the kids' table when they could be sitting with the adults?

As a formerly fat chick, I'm actually kind of thankful to the mean girls I dealt with in my past. Their underdeveloped personalities helped shape mine, and I've parlayed that into a good life while they're on their third or fourth divorce. The really ironic thing is that most of them have gotten super-fat. That wouldn't be a big deal to someone who spent her formative years growing a backbone, a personality and a brain, but for these women...well, it's just the biggest disaster ever. And that's hilarious!

I'm pretty sure the original post was just a troll, but someone who reads this thread might have been bullied by the kind of person you've described. That someone deserves to know that the junior high and high school bullshit only lasts a few years; after that, it's a long, slow spiral into irrelevance for the mean girls.
