I can't bring him to my family reunion

Sorry in advance for the wall of text. I have a family reunion coming up this summer in North Carolina and I was recently informed that I may not bring my boyfriend. I've written up a response, but I don't think I can bring myself to send it to anyone in the family. I wanted to share it with someone though, and I hoped I could get some support. Here it is:When I considered whether or not I would go to our family reunion this year I wondered if I'd be able to afford to take time off work and travel the distance. I never thought to consider that my boyfriend Timo may not be welcome. Yes, I understood his presence would make some people uncomfortable—surely no one would be more uncomfortable than the two of us—but we feel it's worth a little discomfort to spend time with family. I suppose it was wrong of me to assume that I could bring someone without asking, but I was genuinely surprised to hear that he would not be allowed to attend. If I had known that any one person or any group of people had the authority to say who may or may not come, I would have at least made an attempt to go through the proper channels.What surprises me most is the fact that the only reason he is not welcome is because we are in a gay relationship. I'm sure if I had been bringing my girlfriend of 10 months we would be welcome with open arms. There would even be a good chance I could've brought him as a good friend—my best friend—who just happens to be gay. The problem isn't me or him, it's you. I'm sorry your fragile belief system would be so shaken by the presence of a healthy same-sex relationship, and I'm so sad for the young people raised in ignorance to insulate them from a reality that contradicts the false world-view you've raised them to believe.I was very much looking forward to introducing my wonderful boyfriend to my wonderful family, but I guess it turns out my family is a lot smaller than I thought.
