Normally I don't respond to low level comments like this, but the intellectual laziness here is mind boggling. Dictionaries exist for a reason.

...I really, really hope that you are being deliberately obtuse here in refusing to acknowledge that they are asking what you mean by the term to further the conversation. The other option is that you think there's some context where asking a person you disagree with for some kind of objective definition makes sense, and that really, really doesn't speak highly of your reasoning ability. Different people have wildly different understandings of "authoritarian".
