The Stigma of Social Media ... Are all Men Like this?

Lately, I've been having a problem with my self worth. I am wondering how I am viewed through the eyes of others.... this one guy I work with makes a point of stating how he only likes white women and it leaves me feeling like my complexion isn't attractive. He talks about people's weight again making me feel ugly. I have struggled a long time mainly in high school with this. It hurts that it is once again an issue in my life. I know not everyone thinks like he does ... but do most people?
