Being an atheist is ok. Being an atheist and shaming religion and spirituality as silly or not real is not ok.
Being a Christian is ok. Being a homophobic, misogynistic, racist, or otherwise hateful person in the name of Christianity is not ok. Being a reindeer is ok. Bullying and excluding another reindeer because he has a shiny red nose is not ok.
If you put a bee in the freezer, it will get cold and fall asleep. After it’s asleep, put it in your mouth, but don’t eat it. Just let it sit there. It will get warm and wake up. Now you have a bee in your mouth.
