I've just watched the first 10 mins of this documentary. I've read a lot of comments on fb about it over the last few days including a lot of comments from men who are in the camp of the 'genuine good guys' who don't subscribe to it and are as shocked by it as the women commenting, which a lot of women have been reassured by.
Obviously, these men are at the more extreme end of the belief system but, it got me thinking that it's actually a trajectory a lot of men are on. I'd even say most.
I have a partner of 5 years. He is 50/50 on everything including the mental load (believe it or not). We have separate laundry baskets at his insistence because he doesn't want me doing his laundry. He's out at the supermarket at the moment and always does the weekly shop. We meal plan together and write the list together but he'll often be the one who's noticed we've run out of something and he really only consults me to see if there's anything I specifically want (for work lunches or personal items) etc. He does housework, holiday planning etc and I've never left him a list...
Yet, in a conversation about men chasing younger women, he still commented that "most men become more realistic about the sort of woman they can attract as they get older," which isn't the same as preferring someone of a similar age and life stage and finding them attractive. It's about being realistic about what they can get. Eg you might want someone else but you'll take what you can get.
I've dated men who have made a point of saying they "don't mind" a bit of extra weight on a woman but have suggested after a few dates that I'd look better if I dropped a bit of weight (I'm a size 10/12).
Endless threads on here about lazy men who see the household and childrearing as the woman's responsibility. He might not introduce his partner as "Dishwasher" (as someone in the documentary did) but it's certainly who she is to him.
When i read comments on here where women express concerns about a new partner and their mum body, other women will reassure them that he will just be so grateful to have a naked woman in front of him who is willing to have sex with him that he won't care what she looks like or, that men will have sex with sofas so you've got nothing to worry about. Which isn't the positive message I think those women think it is. It says nothing about her as a person only that men will fuck anything so he'll probably be content to fuck her too. I mean, yeah, he'd rather have someone he's attracted to but he is hardly likely to be an Adonis himself so will be grateful for what he can get.
The Manosphere might have taken these ideas to an extreme but it has only taken pretty mainstream ideas/beliefs to the extreme.
These men have not come up with something brand new and that's why it has gained so much traction. Because, on a really fundamental level, it makes sense to a lot of men even if they believe the manosphere takes it too far.
