> Porn is anti-woman.
This is false. Mainstream porn may have failed to appeal to mainstream women, but many women watch porn and many categories of porn are not "anti-women".
> So you're suggesting the solution is to encourage watching porn or others while they have sex?
That is a dishonest interpretation of what OP said.
> It turns the woman into an object.
Does it? I find a lot of porn to be empowering as a woman. I find a lot of time they commoditize the man as just a thing the penis carries with it into the scene where the woman is the star of the show, showing us that we too can be involved in the act, we're allowed to express ourselves. We don't have to just lay there and let the male do his business until he's done. We can get nasty and just have fun. We can even be in charge. You usually can't search mainstream porn by male actor, he's just a prop.
By making sex a super strict taboo while sex is a biological imperitive, you exaggerate dangerous behavior. Having your son not treat women like objects comes from a strong moral foundation in upbringing, not sheltering him from porn and assuming he'll figure out women are people on his own. My dad raised me to be aware of the ways men are likely to trick me, but he also made me aware that the majority of people in general have extremely flawed upbringings. He raised me to be a critical thinker, as such I realize that male sexist behavior is both an individual act and a part of a larger systemic problem. I don't need cheap scapegoats like porn to understand poor behavior in males, I don't need to blame all males when I encounter a really bad one.
Education has been and will always be more effective than zero tolerance policies.
