Someone who gets unbelievably
passionate about
human rights, social change, equality etc. etc. They have strong opinions and (
occasionally) sound theories but do nothing about them. This person only voices their opinion when they don't believe they'll get called out, but never stick to their guns when faced with a situation which challenges the beliefs they care about so keenly.
Sally:"Karen saw someone get
sexually harassed
the other day and didn't say anything about it, wasn't she
going on about how more women need to stick up for each other?"
Ben: "Ugh, she's such a craptivist"
