Ever notice when some women shame men that date much younger women, they'll say things like "he's taking advantage of her immaturity", "he's predatory", "the power dynamics is not healthy" etc.
Here's the thing, these comments are just bullshit. They're a cover up.
The real reason why some women shame these men is because they hate the fact that they are valued by their youth. In a conservative society this wouldn't be an issue as people marry and have kids when young.
But in a liberal, feminist society, women are pushed to spend their youth casually dating, being sexually liberated, chasing careers and college degrees. Not locking down a high quality man.
So what happens when they reach their 30s and 40s and are ready to settle down? They notice guys, their age, who are capable 19-22 year old women, take full advantage of it. This shrinks their dating pool.
There simply aren't enough good quality men to go around for these former, sexually liberated women therefore some become cat ladies.
Shaming is just a tactic used by some of these women to guilt men their own age into committing to them.
That's all there is to it. These women aren't good people looking out for some innocent young girl. They're just protecting their own interest. So don't let the shaming get to you.
