"man up" is an anachronism. it's not something you expect people to say in the twenty-first century, it's something out of a 1950s greaser film - and it upholds outdated concepts of masculinity that are less offensive and more just absurdly outdated.
it's hard to get upset, because it's more comically absurd than offensive. it's like telling a woman to go back to the kitchen - you just laugh, it's ridiculous.
so, this guy is stuck in the twentieth century and doesn't belong on council. clearly.
but, that said, we can't have people hovering over our elected officials and firing them for being douche bags. you just vote this dipshit out.
and if you're feeling cheeky you can tell him to man up to his behaviour.
