That is good for you. I've never even heard of the bands you're talking about - however if the people I listen to espouse a view I dislike, it's no different than a company I buy from doing something I dislike.Obviously she didn't have any because I didn't know who she was (and I even use to watch AI religiously - many years ago - slipped my mind completely)
But this comes from someone who likes Type O Negative, Puscifer and worships Trent Reznor like a God. What a teeny bopper like Clarkson thinks is actually HARDLY offensive to me - everyone has a RIGHT to their own opinion of who they support and don't support politically. But even with my taste - I don't CARE about their political views at all - in fact: for some of my favorite entertainers: I don't even know what they are.
I think it says more (Negatively) about those who judge her rather than she herself who supports a candidate because of SOME views she shares in common - she went against the liberal 'rich and famous' grain and people hate her? That's rather Unamerican if you ask me.
A problem - HUGE problem in this country is that people care TOO much about entertainment icons and not enough about the people who will make the big difference in this country when they're elected into office.
