Unfortunately, just my being a "white NT cishet male" is offensive to some people. I can neither fix that for them nor take it seriously.
No, it isn't. They are offended by something else about you.
How have I personally offended this person, for instance? http://www.dailymail.co.uk/news/article-3054067/Pictured-Div...
I'm a "white NT cishet male", as well, and at a glance, you can't tell the decent people from the awful ones. It's about behavior, and in a space where most people who look like us act like shit, it's not unreasonable to generalize a lack of trust. It's not on them to be understanding, it's on _us_. because we're in the position of privilege in this situation.
