I know that logic (I live for that logic), haha. To me it was slightly different though, I read the books before I got into the fandom etc. And when I did, the opinions about Sirius was either "I like him because he is pretty" or "omg he's such a jerk!!". Both views was so... shallow, it didn't bother me. (If you look at swedish fandom, this is still pretty much the opinion you get. It's quite funny.)
