The following text is certainly appropriate for this time of year:
Being an atheist is okay.
Being an atheist and shaming religions and spirituality as silly and not real is not okay.
Being a Christian is okay.
Being homophobic, misogynistic, racist or an otherwise hateful person and blaming it on your religion is not okay.
Being a reindeer is okay. Bullying and excluding another reindeer because he has a shiny red nose is not okay.No.
Whoever posted this, has yet to learn the difference between an ideology and a person.
Religions and spirituality are silly and not real. We can disagree about that, but why would it not be okay to point it out?
The wording is clearly bad, too. You cannot shame a religion. It's a system of thought. It has no rights or feelings.
Shaming religious or spiritual people, on the other hand, is certainly wrong. Not only is it not okay in the ethical sense, it is factually incorrect, plain and simple.
