If there's a fat at the gym who wants to lose weight and get fit, by all means, I'll show them how to lift, give them tips, etc. I'm very supportive, because, after all, this is how the obesity crisis will resolve, one person at a time.  If you're there for validation, to post selfies on social media, or on some lazy new years resolution trip, or in anyway are making my life difficult, I will shame you to the depths of hell.
