Is it normal that obese people make me angry and and disgusted?

I feel disgust but this due to that fact that I've had anorexia, a phobia, and family issues. I know that it is not fair to judge and try to look at different possibilities. I have little to no sympathy for those eat unhealthy shit and consequently brought weight gain upon themselves. I have no sympathy towards parents who have allowed their children to become fat and make excuses for this. Etc. I do draw the line if the person is fat due to a health issue. Regardless, I don't tease people who are fat because it is very rude. I keep any negativity to myself. Then again, I have told fat people off but these "fat people" in question were family members and I lost my fucking cool.
