Hadn't heard the terms "volcel" or "MGTOW" before but aren't surprised that kinda stuff exists under the MRA umbrella. But if you're looking for a sexless relationship with a women, I'd assume that there's a lot of resources online with access to lots of women who are all too happy to oblige. If that's what's best for you right now, go for it. I'd just try to stay away from anything that reeks too much of MRA bullshit.
"I wouldn't write off girls with little discernable personality in public."
Yeah there've been a few that have surprised me. Was mainly just talking about my own historical preferences. And as far as my friends' significant others, I try not to make assumptions until I've hung out with them at least a handful of times in different settings.
"Having a permanent record of everything going back to 7th grade or earlier sounds like a goddamn nightmare."
TBH I kinda feel like that would actually be the positive side of it. Would love to look back on shit my elementary school self would have posted. It probably would have been hilariously stupid. I'd be far more concerned how social media would affect my social skills and self esteem than people being able to pull up dumb stuff I posted as a kid
