Why are christians always trying to convert me?

its really annoying, they act like god is some kind of weird franchise ive got to buy into to get lots of money in heaven, its bizzare, PLEASE PLEASE stop it, no other religion seems to be so hell bent on turning everyone else onto it.. ive got no problem with christianity, its just not for me (i cant be bothered saying why because ill only offend someone) so stop giving me leaflets telling me how only jesus can save me from the firey pits of hell! i like the warmth, deal with it
