Before you attack me personally, I am 23 myself and haven't ever dated anyone below 20 and have no intention to date women who are much younger than me even in future.

Why shouldn't a 33 year old man date a 23 year old college graduate women?

The most common answer is (even in liberal circles) - any woman below 25 is literally a child, they are immature and can be easily manipulated because their brains (frontal lobe) aren't fully formed yet.

Now, don't lie and tell me that women don't say that. I have seen this reasoning a hundred times (and highly upvoted too) in ppd alone.

There is no study that shows that human brains develop until the magical age of 25. The myth originated from pop culture references and twitter/tumblr. But a lot of people has taken it for a fact and based their entire worldview on that. This is the infamous Alpha Male thing all over again.

An article that summarizes it

Basically according to them, dating a 24 year old is creepy but dating a 26 year old is fine somehow.

Funnily enough, the development of prefrontal cortex doesn't even stop for some people even in their 30s. Are these women also immature, child-like and shouldn't date any man over 30?
