I have a close group of friends that consists of an athiest, an agnostic, a hindu, and 2 christians, and outside of 1 of those christians, we've all been friends for at least 13 years (1 of those relationships since 1994).
No one had to ask the hindu why they got upset when the athiest came by and stood next to the statue of buddha chomping on a mcdonalds beef biscuit.
The athiest didn't think about it, those two had a conversation afterwards, and they still get along just fine to this day (some 10 years later).
This is NOT about beliefs being objective or not. That group of friends has lasted over the years due to a fundamental respect of each other as PEOPLE.
Someone who asks that particular question lacks such respect and as such are not going to be given any headspace by me.
