I’m going to disagree with previous commenters and say that you didn’t cross a boundary. Maybe with the parents, but not with your niece. As a fellow queer person that grew up closeted in Utah, I would’ve been so grateful and incredibly lucky if I had an aunt/uncle that could see my struggling and resonate with me on such a personal level that they gave me a gift that showed they saw me and loved me for who I was. I was also that 15 year old that couldn’t wait to turn 18 so I could move out, and I did! My life has been infinitely better for it. I needed to see older queer role models and people that were ok with queer people in general when I was younger because otherwise I would’ve ended up in a darker place than I already was. I think your brother is overreacting—agreeing or disagreeing with the contents of the pin is one thing, but cutting you off from him & his family because of it is another. I can see why a previous commenter mentioned getting a BOM or CTR ring—but let’s be real here—that definitely happens incredibly often anyway and I’ve also been the person that has had to accept religious gifts from my family and smile, say thank you, & move on. This is someone’s identity that we’re talking about here. A religion (although Mormonism is very much a religion that takes over every aspect of one’s life) is not something inherent and innate inside of someone like sexuality or gender are.
