@0x4d6165 I agree that acting this way is asshole behaviour, but I wouldn't dismiss this as just arrogance.
I was like that when I was younger, it was stupid ofc, but it wasn't because I felt superior or better than anyone, it was because at the time a lot of religious people I personally met acted that exact way towards me, so I just began thinking "Well they treat me this way, why shouldn't I do the same?"
In the end ofc it was stupid and I was sometimes bit of an asshole, but being called arrogant and feeling superior was one of the things that also made me mad, because it was feeding into the feeling of "They feel superior all the fucking time, but suddenly I am the bad one?"
So while yes, it has to be pointed out, it is bad, I think dismissing it as just sign of arrogance is a bit similar to the "you don't know why they believe what they believe" and it just furthers the division.
Unless they are active on r/atheism or whatever then there is no hope
