You're wrong about that assumption, it's just that there is no point in stepping up when it will just give others the Jesus is sending you to hell kinda appeal, which is exactly what many people want to stay away from. The internet has very poor communication, a very bad place for any discussion about faith or anything of the like, it just ends up with everyone mad at each other.
I never have, nor will say that Jesus is gonna send anybody to hell.
How am I supposed to know whether he is or not? Plus, that kind of thing is exactly what I want to stay away from as well.
However, that does not give way to twerps like him who think that because "no one cares" they can just flame whoever brings up religion, flame people for their beliefs, and flame people for not believing the same way they do.
