Doctor Carrot
Marxist Henchman
It's a straw man. PUAs. Losers who join a pick up girls site, and then get blamed for all of the world's ills.
Who exactly is doing that? All I see is it's been pointed out that this murdering twat was part of the whole 'manosphere' scene which, undoubtedly, is misogynistic, self entitled, self important, ego centric, treats women like pieces of meat with the odd feeling here or there, or in PUA terms 'bitch shield/bitch test,' that need to be 'hacked' with certain tricks. Do I blame that entire scene for him going on the rampage? No, do I blame that scene for stoking probably already pre existing feelings of self importance, entitlement and so on in said murdering twat? Absolutely.
PUAs and the like are not the cause of all the world's ills as you put it, no, they're a symptom of an individualistic, self important society that peddles the bullshit of 'you can get anything want if you just try hard enough and do the right things because you're a special little snowflake who deserves the best.'
