That’s one of the problems with being unwilling to actually point out the actual posts that you call “posturing”. Since you make a blanket accusation, you end up accusing everyone.
I’m sure you see the atheistic posturing posts, but as two posters have already pointed out that they felt you were talking about them, when they were in no way doing as you describe, why don’t you go ahead and actually back up your statement with the posts that you find so offensive.
