“weird” is an effective way to shut down right-wing nutjobs because they care too much about conformity, and are likely to change their behaviour if they believe they are going against the will of the herd. it undermines their whole ‘silent majority’ schtick.
all this to say, i’m autistic, i’m weird, and i don’t think that this new strategic use of the word in politics should mean you shouldn’t use it in other ways too.
