this argument is not valid. why: (always take the extreme example) so you wouldn't disrespect Hitler because there are some people that worship him?
u see, if it's someone's opinion that religion is a big bullshit (very reasonable btw), then this person has every right to point this out.
Maybe it's just me, but I don't think disrespecting Hitler is the way to get anywhere let along express an opinion against his actions.
But hey, I must agree that you make a good point.
And tbh, I also think religion or at least its big entities are a big BS, and I believe everyone has the right to point this out! Please that's a basic right. But that image simply is not the way.
