Ok, so you’re the genius who never does anything that doesn’t make completely logic sense because of traditions, culture, upbringing or even just making mistakes, as opposed to every single human society in history. Not sure why you brought up that particular practice which is abhorrent. Presumably you are against people wearing crosses, tattoos of significant people or events in somebodies life, football shirts, or any other symbol of something to care about.

I say this as an atheist by the way. I don’t believe in religion but who am I to tell people the beliefs they care about are dumb without knowing anything about them.
