It looks like what I posted might not have been clear. I mean: please don't use quotation marks to make it look like you're quoting someone when you're not really quoting them. In particular, please don't do that thing where people sarcastically put words in someone's mouth and then add quotation marks around those words to amplify the rhetorical effect.

Uses of quotation marks for quoting someone, or for doing something that doesn't look like quoting someone (e.g. "self-referentially") are fine.
