Type in 'why men are not dating' etc into YouTube. Much of it is often spouted as incel stuff, but it basically goes like this: (generalisations):
Women are independent these days. No need for a man. Who wants to not be 'needed'.
Women these days are taught to hate men. Men are the root of all evil.
Promiscuity is rife. Who wants a woman with so much 'history' (competition).
Given all that promiscuity, who wants to risk raising a child that isn't theirs.
Independent 'boss babes' are argumentative, controlling, demanding...
Women still marry 'up', yet initiate 80% (often spouted) of the divorces. Strategic marriages for money.
The 'men just want bellies full, balls empty, and a peaceful life' line.
Many women still 'expect' the man to pay, yet have their own jobs. His money is my money, my money is my money.
So if you're supporting her, what do you get in return? Many women these days can't/won't even cook.
Sex is basically said to disappear after marriage. Why be tied down into something sexless.
What can a man get in a relationship that he can't get being single.
Men are being shamed while women are being supported. A fat man is ugly, a fat woman is 'rocking those curves' etc. Similarly, if a man gets fat during a relationship, he's lazy, but a woman can balloon after kids, never lose it, look nothing like the woman he married, and he's meant to be ok with it.
Workplace culture says it's 'safer' to avoid women all together. One 'safe' joke you could say with 99% of men, you can't say with 99% of women.
Similarly (MN is a great example), half of women HATE men approaching them, and many will actively shout down and berate men who try. "I'm 40 now and it's such a relief men aren't approaching me anymore" sorts of lines. The rest of the women are wondering why they no longer get attention. Why risk it.
The 90:10 rule. Due to OLD, women can be super selective. 90% of women are aiming for 10% of men. They will probably end up all sleeping with those 10%, because why would those 10% refuse sex with all those women. This gives those 'average' woman a hyper-inflated sense of self worth ("I once got a '10', clearly im a 10, I deserve 10s now!"). They all end up holding out for 10s, ending up bitter because those 10s are just after one thing and will no doubt have cheated on them OR theyll find their man and now have that feeling like they've 'settled' for average... even though they themselves are average. So what man wants to be the one they settle for.
Plus the MN double standards... In a sexless relstionship a man can't 'want' sex, he's a sex pest. If a woman does, she has a right to be happy. A man not wanting sex MUST be a porn addict/cheating. A woman deserves oral, but a man has no right to it.
The infographic attached. Who wants to risk that?
This is what's being spouted on the forums etc. It appears to be the general 'vibe' out there. It's not exactly conducive to relationships.
