Mama's boys

This phenomenon definitely happens more outside of America, in highly misogynistic countries, which I am so sympathetic that you have to deal with. I could not imagine what you're going through. It happens in US too. But to a much smaller degree. And with my mom, she never wanted boys. She only wanted girls. So I was lucky that she never favored my two brothers over me. She loved us all the same.

You have pretty good points there!

I'd be especially wary about men who don't have any siblings or who only have sisters (doubly so if he is also the youngest child). They are the most likely to turn into spoiled little princes and Momma's boys in my experience.

I don't mind it if he has a good and close relationship with his parents and long as it's reciprocal (aka he also helps them out in meaningful ways instead of just letting mommy do his laundry) and there are firm boundaries that are respected by both sides (e.g. no dropping in unannounced).

Hmmm idk about having this firm boundary. Yes some mothers will be like this, and you see it in this Discovery channel show. But my mother was a single mom and never discussed sex with my two brothers. I mean, the vast majority of males were raised by single moms and they don't do that. Two parent households are rare these days. But this show does highlight how Mama's boys are a particular toxic type of male.

I don't know that I agree with this. All of the Mamma's boys I know actually have married mothers, not single mothers. These guys mothers were housewives with no lives outside of their children, which is why their sons are so coddled. I think a better approach is to actually pay attention to the son's relationship to his mother rather than making assumptions based on whether the mother is married or not.
