>But I do wonder, how do you feel about reading books you own?

Bit late to this thread, but I can chime in here. Learning about Card's beliefs made me not want to read his books anymore, even though I'd enjoyed some of them.

I only ever had his books on Kindle, but I used to own several novels by a somewhat famous author from my country, who eventually came out as a racist and misogynistic asshole. The kind that gives speeches at rallyes. That was reason enough for me to ban him from my shelves, because I knew I wouldn't read those books again and I didn't want to be associated with his bigotry or seen to be tacitly endorcing his views by keeping them. Originally I'd planned to sell them and donate the proceeds to a charity that works with female refugees, but I couldn't find a second hand shop willing to take them. In the end, they landed in the trash and good riddance.

I haven't been able to stay away from my Harry Potter audiobooks, but I make a point not to spend any money on their author. No movie tickets, no "first hand" buying of books or merchandise.
