maaaybe i’m a feminist killjoy and freedom-of-speech oppressor who “can’t take a joke”

Never apologize for your fluency in english.
If you have a different mother tongue, you are under no obligation to know english at all, let alone fluent english.
Never let anyone make you feel bad for not speaking proper english.
Be proud of your mother tongue.
Why should we learn their language when they mock and refuse to learn our own.
