From what you have shared, it sounds like your husband doesn't want to be around people that say things that encourage him to feel bad about himself. It sounds like your parents have continued to not only disrespect him with their comments, but they are also disrespecting you as well.

I imagine that it's hard enough to deal with the stigma that tends to be pushed so much in our overall political arena from "both political parties", but to experience this personally which is what your parents create for him, can be VERY depressing.

Unfortunately, human beings do tend to "stigmatize" and embrace the all X's are bad mentality. Years ago the italians went through it where italians were stigmatized as being part of some mafia crime family. The Germans were stigmatized as being part of the many that followed Hitler's crazyness. The Jews are STILL stigmatized in an often very negative light, same with the Russians and the list goes on when it comes to stigmatizing including all whites tend to be racist and prejudice.

Perhaps what your husband feels is that you did not really stand up to your parents, and maybe because you still want to be around them for the Holidays even though they have proven they can be so disrespectful to your husband and even YOU has hurt him in a way you are not really understanding. Your parents should be respecting the person you love and married no matter what he is and does that he finds rewarding. Seriously, who are your parents to think they have a right to judge what another person chooses to do with their life by embracing something that makes them happy? There is absolutely nothing wrong with choosing to be a college professor either. Lots of good people are actually drawn to and flourish well in an educational environment.

Why can't you spend the holidays with HIS family? Actually, think about how you would feel if every time you were around his family they made you feel like you are just another racist prejudice person? How would you feel about being dragged to visit his family when you constantly feel so unwelcome and like you simply don't really belong?
