Most men communities talk about it in one form or the other. However, most men communities on the internet are usually close in one form or another to the right politically.
It is a shame that any group which advocates men's issues tends to get labeled as right-wing or incelish, which then attracts those types and makes those labels a reality. And of course many were admitedly that way from the start.
Edit: And to add to this, being right or left leaning isn't inherently bad. And maybe this is my personal bias coming into play here, but I find that people are much quicker to associate right-leaning movements/communities as "bad" than they are left-leaning ones. Again I accept that could be personal bias and it isn't a hill I'd die on.
The incel label is a good example of how bad men are treated sometimes. If you treated poor people like this by saying they're involuntarly not rich and then proceeded to say that it's mostly their fault because they don't work enough, think they can just show up to work, do their job and become rich, shouldn't expect money to be given to them, most people would react by saying that you're wrong. And when some parts of the population have trouble having sex/companionship like some trans people, it's called discrimination. But the same rules don't apply to incels it semms.
As to whether or not that group is popular... this is an interesting one since the bonding factor is a lack of relationship success (which is closely related to, but not the same as, popularity) in the first place. But if you look at a lot of how the group that has gathered under that label interacts with the rest of the population... it's hard to say it's just something like mocking them for not being able to get laid. There are a lot of frankly offensive and violent theories pushed by people out there.
It's deeply ironic actually - "I'm not having sexual success, I'm going to start listening more to other men who also have the same problem, they're the ones who will be able to tell me about women." Back when it was a more ironic, non-violent "foreveralone" meme I was in the club... it wasn't increasing my exposure to men that eventually got me out of it.
