Yeah same here. I like music for music, I don't care if I agree with the politics if the music doesn't interest me. And vice versa I can love a song even if the lyrical themes are not something I agree with politically.
I'm not a vegetarian and preachy vegans annoy the sh*t out of me, but Jon Anderson is a vegetarian and vegan themes are brought up in Tales From Topographic Oceans but I still love that album.
There is music I love that has very religious themes even though I'm not religious. I listen to anarchist bands even though I'm not an anarchist, I listen to socialist bands even though I'm not a socialist, I like republican bands even though I'm not republican. And I can go on.
I definitely draw the line with artists whose lyrics promote stuff like fascism and racism though. But I've never found a band who does that and actually makes interesting music. All those nazi punk bands are crap.
With sexism I dunno, there is a little bit of it in a lot of music even in great music, I mean I rant all the time about how men treat women and sh*t and I contradict myself because I listen to c0ck rock and gangsta rap all the time.
Music comes first for me, I don't get people who reject or endorse a band entirely because they have a different point of view. A lot of punks seem to care way too much about the political message and little about the actual music.
