In addition, I lament that it is iillegal for men to have their own organizations of any kind. It is not legal for men to have their own clubs or organizations in the Western world. It is illegal for men, and particularly white men, to self select and self organize. This is a factual statement.
I do wonder how this will play out in the end.
Creating accounts to post like this will eventually get your main account banned as well, so please don't.
I don't think it's "illegal"; the problem is that these kind of organisations tend to veer towards the toxic and hateful.
Incels are an excellent example of this; the entire concept was started by a woman struggling with her own involuntary celibacy and started a support forum. Good initiative. But over time things have become ... well, rather different.
A lot of the so-called "men's rights" groups have some legitimate grievances, and I have seen more than a few outspoken feminists underscore this. But having legitimate grievances doesn't excuse their terrible behaviour and attitude.
There are some decent groups for this; /r/MensLib on Reddit is pretty good. But the average is not exactly great.
My own view is that I have no problem working with women (though there are some women I would refuse to work with or be around in a social setting b/c of the risk). I suspect I don't mind because I've had a positive experience working in a research lab were the PI was a female, as well as one of the research assistants that I closely worked with: I did one aspect of hardware/software, she did the other.
