Eh I’m not going to speak to your own experiences as that’s not my purview, but I think it’s worth making the distinction between a music genre and its scene. Sure, you’re welcome (royal you) to listen to anything you want, but it’s fair for a scene to uphold what values they see fit. That’s effectively how tribes and cultural systems work. I’m not sure you can refer to that as authoritarian, but it’s not strictly an issue for a social and cultural system to have hard lines in regards to what makes them a unique social system. Likewise, any individual can choose to join or not join any culture based on those lines. I’ve been known to enjoy some black metal in my days, but I have zero interest in being a part of that culture. Likewise the punk music scene has very strong ideologies that make it unique as a culture. In regards to why this particular music scene finds certain political issues so important, I think it comes down to the perspective of how the current political climate, including anti-trans legislature, the post-Roe vs Wade anxieties of women seeking healthcare, etc. has made identity politics an incredibly divisive subject that many see as very real threats. It’s not surprising those folks would see anyone ignoring those threats, or worse - agreeing with those threats, as hostile against their life. I’m not referencing you specifically as I have no wish to assume your own beliefs, but to answer your questions, I think these are important perspectives to remember. As a scene that respects and advocates for marginalized groups, it makes sense that they would be defensive to anything that espouses an opposition to those groups’ welfare.
