You do realize that the only people who actually say things like this are conservative jerkoffs posting hyperbolic strawmen because they are flabbergasted at being asked to have the decency to address those around them as they'd like to be addressed, right? No one* is going to react like this to an honest mistake, especially where pronouns haven't been specified.
Getting someone's pronouns wrong doesn't make people think you are a fascist bigot. Mocking the idea of trying to get pronouns right, on the other hand...
*Actually probably someone would, because no group is without its assholes. But, you are going to have to work hard to find someone who will actually respond like this without provocation.
