Please don't give me flack based on me knowing, but the guys and girls on /r/fatpeoplehate often talked about not only the increased medical costs, but a lot of the issues that were had were things such as nursing staff and EMS employees being physically injured and unable to work due to having to move/lift obese people. Also there were many people who were upset by people who they worked with stealing lunches, being obnoxious about eating, or being rude seeing that they weren't "eating a man's lunch".

It's easy to see /r/fatpeoplehate as its name, and at its core, it is just a hate sub. But anyone who looked through the comments would see people who are frustrated and just need a place to unload, and it was by far the most tolerant sub I've seen. Didn't matter if you were gay, trans, muslim, or any minority. As long as you weren't fat, you were seen as not just another person, but as brethren. You were also a shitlord.

What I'm trying to say is that most people seem to think if you were to subtract the fat people from /r/fatpeoplehate it would just be an angry group of trolls looking for something else to be angry and hateful about, but at least from my experience, it was a safe-haven where everybody was truly equal, and everyone was valued.
