At the risk of sounding pretentious, I call it "socialist", since they spend their lives telling others what to do or what is good or not for the rest of us but they rarely do anything about it. Surprisingly, this is the group that is really worried about poverty and climate change and do as much as I do for it, with the difference that I do it by myself, the few times I do it, not requiring the rest to do it.
It is always someone else who will do it. Though the other day I had a conversation with a non-socialist person that had that same attitude ("other should do it") towards what OTHERS should do. I really dislike that attitude, no matter where it comes from.
Point at hand: when I want or promote something, I am the first one to do it no matter others do it or not. The rest, no matter the ideology, all b*llshit.
As imperfect as I am, I try to do what I think is good (and sometimes my imperfection prevents me from doing it) but I do not spend my life telling other people why they are worse than me and telling them what they should do or not. The most I have for someone is good suggestions, never requirements.
