Yes she is, fat people aren't attractive in the slightest. Being a fatass shortens your lifespan by giving you heart problems and diabetes. Diabetes is literally your bodies way of telling you to stop being a fat f**k
Dude, this isn't about being attractive, and if you think it is, you must be stupid. I'M not attractive in the slightest, but I'm not fat. Your weight doesn't determine beauty.
Also, that's your opinion. You don't need to tell her about it.
