I fear being called racist
Thats an interesting fear to have but how did this come to be?
Several years ago, my teacher told me that I will become a racist and that I should fear this.
It's good of you to be worried about that.  Did you ask them what you can do to come off as less racist?  Because I think that would've been a smart move.
I think that's something I addressed in high school. I came off as less racist during college
Thats  great. If you feel like you still need help you might want to talk to someone and work on your socializing skills. That way you can put it all behind you and not have a fear of being racist anymore.
