gollark: Great!
gollark: That's not actually what I said.
gollark: I failed to come up with a non-politically-charged example so I'll just use a horribly politically charged one: people arguing over statements like "abortion is murder" is pointless, as you're basically just arguing over whether you get to associate it with bad things or not, instead of getting to the actual underlying questions about, say, rights of unborn babies.
gollark: It doesn't help your argument, or help people more accurately think about the actions, or whatever.
gollark: I am talking meta-level here; I'm not saying "culling is unhelpful" but "it doesn't actually help anything to try and shove things into the culling box".
