I see it like this... yes, we all objectify women at times.  Sometimes that falls on the appreciation side, sometimes its over the line, always driven by literally the greatest drive we as humans have (survival, hence procreation).
A lot of this, even parts that may be a bit unseemly, are natural.  Doesn't mean that's good per se, as violence has roots in natural behavior as well... but it is what it is.
But that doesn't mean this forum should 'encourage' it, either.  Also doesn't  mean other platforms might not be better suited for the raunchier side of things.
While hardly a perfect analogy, we make off colored jokes, even racist ones even that may be ok within some context... but won't fly here, or in other social situations. In this case, let's be honest, those threads were not knee jerk/instinctual responses to our natural desires.  They are there to objectify, comment etc in a way that can certainly be seen as degrading and at least with some lack of respect (and again, I gladly partoke, and likely will do so in other forums/situations moving forward - and most of that's probably ok, some of it? Probably not my best work)
There is no "right" or "wrong" here - and it's not about being too little or too much PC. It's about finding what is appropriate for these boards, which have always aimed for PG.  I liked those threads, but I get that perhaps its best that we move on from blatant 100% pure objectification here that borders on having little to no respect for the "person" and a level of discourse that might follow that lead.
