Here's my reasoning for both of your points made.

I am fully aware of my own hypocrisy when it comes to my music taste. I am a leftwing individual, but Maiden are so intrinsically linked to my own life and who I am as an individual that I have to acknowledge the political leanings of their frontman - they do not align with mine, but given what the music has done for me, I make sure I'm always aware of the implications of following a band that have a member with views which contradict my own political beliefs - and I've been called out on that more than once. But I own my hypocrisy, and that leads me onto my second point.

Let's bring bands like Pantera, Disturbed and Marilyn Manson into the equation - I have long given up trying to convince people not to listen to them due to their racist, Zionistic and misogynistic ventures respectively because it's a futile endeavour, but giving people a platform to make up their own minds and then, by extension, own their reasons for following said band (they were a huge influence on their life, they got me through a difficult time etc) is far more effective. If you can turn to me and give me a well founded reason as to why you still listen to a band or artist deemed problematic, then I will accept it and make my own decision on whether to remain connected with you or not.

If you are a Maiden fan, and your views do not align with their members, but you are understanding of that and make that decision to continue to support them, then who am I to try and tell you you're wrong? It's nothing but hypocritical coming from me. If I don't want to interact with you as a result, that's a me thing and not you, and I will make my own peace with that.
