...and saying youve got a headache is just like murder
Its not logical in the slightest, its a hangover from the church when the power of the church was in its numbers so the more kids you had the more power. Early christianity was political in most repects, even the religious holidays were timed to pagan events to make converting people easier (jesus was born somewhere mid november but there is a pagan ritual on the 25th and the roman celebration of the god of chaos ended on the 24th *i think*)
contraception is preventing life the same way that a blow job is so arguing it is fairly silly unless you find a religious fanatic (which is unlikely on this site - try prodeathpenalty.org

).
I wonder if as male contraception methods are more accepted they will be considered the same as female contraception. Given surgical methods are mostly reversible now and getting cheaper it wont be too far that guys will be lining up to get rid of the chance of shot gun weddings and child support
