It's insidious. It started with the whale tears to silence the shaming, and curb the sideways glances. The "if you can't say something nice, don't say anything" PC mentality took root across our culture. Then came the early fatlogic about genetics being the deciding factor, which many people fell for (and still do). I, myself, fell victim to this thinking for a long time believing I was just naturally skinny, until I noticed just how much lying was going on around me and I realized I wasn't eating near the amount they were. Now it's flipped around to the point where we live in a culture where I'm an evil incarnate asshole because I refuse to date fat women.  They manipulate others into their traps. "Go ahead and have another piece. You earned it." They sabotage the efforts of others who try to lose weight. As their numbers grew, they got bolder. And now we are where we are today with FA & HAES bullshit.
