It is difficult to present a case against religion and not sound offensive to theists, from the get go that one pronounces their lack of belief, there's mistrust and ominous feelings towards the atheist. Theist feel threatened just by the knowledge that a particular person they know is an atheist, be him/her their own family member or just a friend.
Theist confuse the atheist, non believer as being deluded, sick or in denial of what they think is obvious, they are right and fundamentally the atheist is plainly wrong. Theist are beyond the reach of reason or logic, as been demonstrated throughout this forum and others all over the web including YouTube rants against atheist pro's and cons of the argument.
Theists feel threatened with the new surge of atheist fire that is rising throughout much of the free world, and unfortunately they've got the guns, the politicians, the media, and an overwhelming number of ignorant masses believing that theirs is the truth of salvation.
So yea! man when they come to a scientific forum, we feel that here, we got every damn right to bitch, call names, and even get a warning every once in while for being too damn direct! Just call these forums stress therapy, we get out our frustrations here, dumb ass arguments are really not much tolerated, we see them on a daily basis, this is science, this is where they've got a chance to present scientific empirical evidence or at the very least a logical argument for their ideology which basically is a bowl of shit in the scesspool we call the world!
