I've felt that way since season 6 when all the 'picking sides' business just got too much and right now I'm at the point where I'm starting to de-friend/unfollow fellow SPN fans on various social network sites because I simply can't stand it anymore.

Everyone is entitled to their opinion but I for one am apparently one of the very few people who is really enjoying season 9 (and I'm also always at least a day behind; usually it's more like a week or so) and every time I'm like "Oh I liked that!", all I see around me are people saying who is an awful brother and what storyline sucks :/

I can really understand how that would affect your writing. It'd kill all my inspiration as well.
