Calling others ugly does not make you any prettier or handsomer. Calling others fat will not make you any skinnier or fitter as well. When you discriminate and say someone is gay and such, it does not make you any manlier or macho-er in any sense as well. Bottom line is, it does not matter what people says about you. As long as you stay true to yourself, you will go far.
I mean, no ones perfect right? So chill. God is great. :)
