"Benevolent sexism is still sexism.
One the one hand benevolent sexism demeans and on the other hand malevolent sexism actively causes harm.
The very notion that women being provided for/protected by men is somehow a good thing is massively damaging to women.
It is in no way a positive thing. It involves infantilising women."
Yes agree, of course it is infantalising and generally sexed stereotypes of male or female are reductive and prevent people from behaving according to their humanity as individuals.
I have no argument against your description of rape and violence against women as being inherently driven by a form of masculinity.
However, my original point was that the idea of using a prostitute is one that would jar with most men who society would consider as masculine (benevolently sexist as you describe) While the outlook of men who see themselves being a protector / provider infantalises women, they do not see women as hateful objects to be dominated via sex and violence.
Obviously, un-sexist men who view women as human beings would also not wish to use prostitutes but my post was responding to the poster calling himself an MRA who questioned why his impulse was to not want to use prostitutes. My response was to share my opinion that even viewing the world through an MRA lens, using a prostitute essentially equates to a failure of manhood.
I agree that the misogynist murderers and rapists and men who use prostitutes are also conforming to masculinity but would see this as representing the darkest end of the spectrum of masculinity.
