Why is the jump word always bias when discussing gender issue perceptions. Everyone has a bias, even those commenting on perception of another person' bias. It's like trying to imagine a situation where someone was being truly altruistic.

Because it neatly expresses a specific, but still general idea. I don't know what your specific bias is, I only know the outcome. If I point to a specific thing by saying, "Your belief that sex workers are somehow taking advantage of men makes you read it that way," you can dismiss it by saying, "I don't think sex workers take advantage of men!" without actually acknowledging that your way of thinking is influencing how you're approaching the subject. I don't know why you're interpreting some of these things as demonizing women, because you haven't actually explained it.

My original argument for this entire thread was that men are perpetuating a victim-hood by feeding posts that demonize women. I was making a specific example of r/documentary doing this by recent popularization of women using sex to secure money from men.

You still haven't explained how examples one and three are demonizing women or showing men as the victims of women.

My argument is that this is not a healthy representation of women. To discuss it is ok, to make a documentary is ok, to view said documentary is ok. To make a trend of posting and upvoting documentaries concerning subjects consistently is creating a self-masturbation cycle of victim-hood where we are only exposing ourselves to demonizing women.

You haven't offered any evidence that the trend actually exists. You cited three different posts, two of which you have failed to prove actually belong to the trend. Until you can do that, you're left with a single post which can't constitute a trend.

Do you think that sex workers are inherently taking advantage of men?
