I'm in the same boat.  I don't go in for the wanton hatred of every fat person whose ever lived.  But it started to seem that it was wrong or bad of me to find overweight people unappealing, as if there was some character flaw in me.  And as the HAES and FA movements began to pick up steam (admittedly, mostly on the Internet) we've watched as fat people try to escape any sort of responsibility for their predicaments and instead force the world around them to change.  HAES and FA are poisonous ideologies and need to be stopped.  That's what brought me to FPH.
