Some Christian people (not nearly all) think that the correctness of their belief system is so obvious to everyone, that those around them will be inspired to bend over backwards to help at the mere mention of the fact that the person is a Christian.
It is a weird phenomenon and it usually has the opposite effect on me because it shows that the person doesn't even understand what his/her own religion is supposed to be about.
Yeah, I agree, Christianity is not the magic ticket to get whatever you want - kinda the opposite of the Bible's teaching on the subject, actually. Makes me cringe when you see stuff like that original thread: he's choosing to be a representative of God (which I believe that Christians are), but is in the process demanding that we or Mozilla or whatever bend to his will.
