Unfortunately, as soon as a person starts engaging the all X's are mentality, it's bound to cause problems. It's very possible your parents really respect and like your husband. They have tried to have an open mind, yet, what probably bothers them is being accused of being bad because of their skin color. NO ONE likes to be treated badly due to their skin color no matter WHAT a person's skin color is. The truth is that TOXIC/BAD people happen to come in ALL COLORS when it comes to human beings. Most likely, as is often the case is your parents were not able to articulate how they felt in a way that your husband could find acceptable and it ended badly leaving both your parents and your husband triggered and upset.

I have to be honest with you in that in my business I deal with all kinds of people, all different classes and nationalities and colors. Yet, after Obama won the presidency I ended up experiencing a couple of situations where I was at a gathering of African Americans and suddenly faced the "you white people are going to pay now" comments directed at me. I had a student with me as a helper and she was so traumatized she cried all the way home. And another gathering I was literally surrounded by African Americans refusing to pay me. That time I ended up breaking down into tears due to developing ptsd and I was trying to work despite struggling so much. Why? Just because of my color and now I need to face anger even though I myself never treated these people badly? I never faced that kind of treatment before and had worked with many groups of African American individuals over the years with no problems. I thought it was great that we finally had an African American president, it saddened me the anger and resentments I had faced, that I had not faced before.

That being said, I have faced rude and disrespectful white people as well while doing different jobs. So, it's not JUST about color. Yet that did change and began to lead to my feeling uncomfortable due to the trend of "white hating and blaming". As long as people do the "all X's are bad", it's going to lead to MORE problems IMHO.
