gollark: You can maybe be *practically* non-political, if you just somehow avoid letting politics affect your purchasing decisions.
gollark: Hmm, okay then. As in, a big dropoff right after that happened, or just a general decline around the same time?
gollark: You seem to think that laws drive social attitude change. I think it's somewhat the other way round.
gollark: You should say it that way initially then. It's clearer.
