You should be allowed to mock whoever or what ever you want, as long as it isn’t inciting to violence or anything illegal.
Its the joy of living in a free society.
Why shouldn’t we mock them ? We mock Jesus, we mock scousers and brummies, plus a whole host of other types / colours/ backgrounds etc etc…..
I’m bald with a beard , im going to get overly offended and demand respect the next time someone says I’ve got my head on upside down !!!!
