The head canons are insane lmfao.
If a progressive school is sending you to the office for saying Christmas, they’re probably just going to have a chat about being more progressive with our well wishes to include everyone.
You wanna exclude people that’s fine, but don’t label the people trying to be the most kind as insane or assholes. lol.
happy holidays isn’t more inclusive, it’s just generic. i feel included in a community when they salute me as they would with one of their own
Which is what you’d use if you didn’t know what religion they practice if at all
Otherwise, sensibly, you’d wish them a happy whatever it is they celebrate.
Not everyone is cool with having their religion assumed on so it’s not “generic” it’s respectful
I don’t know. a Muslim once saluted me with the end of Ramadan holyday. that day i met a friend. parted ways, we still greet each other when we meet. dude did not assume anything about me, he just wanted to share and make friends. being greeted with one’s culture and being not ok with it, it means you’re not an educated person.
