Without giving away my age (But I do predates smart phones and home internet use), I've found men are perfectly fine with venting assuming the setting is right. Small group? Beer? Sure. Something embarrassing happens in the moment? Not so much.

Its everyone but your male friends who will give you shit for showing any emotion but anger.

To be fair, who said it wasn't also men?

anecdotally, as a guy in my thirties, even my acquaintances (wouldn't actually consider them friends tbh, since we only hang out at rec game times) are quite supportive. sure there's the surface level of shit talk, but if you start to get serious, they do too. a few of them surprised me with this.

in my experience nowadays, it's equally just shitty people of any gender that say suck it up, no real bias one way or another

but that's of course just my own circles. I tend to just drop out of (or not join in the first place) any circle that has shitty people

In my experience, when a man complains about their 'men' problems to anyone online they're given the treatment grueling_spool is describing by both men and women.

But in more "insulated" face to face conversations its pretty varied/mixed. I suspect this is mostly an "all to all" online conversation effect. There are people who are absolutely ruthless online towards men complaining about problems men specifically face and they will find complaining men and mock them.

For sure, women usually say they want a man who can show his feelings. It's just that the second he does cry about anything other than a dead child, she gets the ick and loses all respect for him, in my personal experience. I think they talk a big game but when the chips are down they find out they're not actually as into it as they thought.
