I wouldn't go that far, because I know some people that had for example bad childhood experiences with aggressive dogs and I kinda get it for them. I assume it's the case for some users of this sub, but there are also clearly some people there that just have weird brainworms.
These people are bad but i'll take them over anti-natalists. Alot of anti-natalists will actively argue against child welfare and education spending because its public money that isn't being spent on the virtous child-free couples who are trying to go r/leanfire. At least this is partially taking the shit out of these people even if it has it's own anti-social bent to it
