Because they mostly all have terrible personalities and would find each other totally unbearable just like the rest of us do.
They also generally don’t really want to date any sort of actual human that exists in the real world. They want to date a perfect parody of the opposite sex, incels are looking for someone who looks like Barbie (or whatever their idea of a perfect body type is, some go for a the petite almost childlike look after all) who wakes up looking like she just left the salon, who is totally subservient to all of his wants and needs, never speaks up unless it’s to stroke his ego, a perfect cook and maid, an oversexed freak in the sheets, who will bear however many children his twisted ego wants to inflict on the world but never gain a pound or show any stretch marks, wrinkles, or grey hair
In short they don’t want to date a real person, they want a real doll who does their laundry and squeezes out children.
And they’re convinced that these mythical creatures exist out in the real world but that someone is conspiring to keep them from them, because obviously they’re the perfect example of masculinity and why wouldn’t these perfect females be flocking to them otherwise?
And I’m not certain exactly what sort of fictitious Superman feels are after, but the same overall sentiment applies.
Or else they’re just deeply in the closet.
You got a typo for mastodon (mastadon)
I don’t really have any input on how it is to self-host, but I’ve been playing around with friendica a bit and I think that has a lot of potential and may be worth mentioning. I think it has a lot of potential as almost a unified fediverse portal in addition to its obvious purpose of being a Facebook alternative, from what I’ve seen it seems to play pretty nicely with a lot of other fediverse services, and also supports RSS feeds
It needs some polishing, I think the default UI is pretty wonky, but there’s a lot of functionality there if you can be bothered to figure it out.
