As a staunch Athiest... my 19 month old daughter also has a noahs ark toy, because, y'know, all she sees is a boat with animals and stuff to play with.
Despite having a dalliance with christianity in my formative years i've never really understood the schsims which seem to exist within the christian community
I see things in a very black and white way.
Either the bible is the word of god and should be taken as such...
“… from infancy you have known the holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work” (2 Timothy 3:15-17).
or it isn't , in which case i'm not sure how anyone can base, well, anything on it.
So lets pop down the 'rational' route and accept that the bible is the word of god. If we have an omnipotent and omniscient god then we have to assume that he's not going to cock up his book.
Which makes me think that the bible should be read as the work of an infallible god or, otherwise, what is the point.
So we should be taking this literally, which is where the hating of gays comes from. (and many more troubling verses)
The major problem comes from proselytising but that is also backed by the bible - so all christians should be doing it
"I solemnly charge you in the presence of God and of Christ Jesus, who is to judge the living and the dead, and by His appearing and His kingdom: preach the word; be ready in season and out of season; reprove, rebuke, exhort, with great patience and instruction.(2 Timothy 4:2)"
and then also the wars and terrorism which have been waged in (various) gods name. Without the religious justification these people are just bellends and it is a lot harder to rally a group of people with disparate beliefs than a group with a common belief
Unfortunately the same way that 'all' muslims are being tarred with terrorist labels, christians will also get lambasted because of what minorities within their community do.
oh and don't forget that Athiests have no morals, but some do actually try to be nice to people whilst they are here and alive - not because of some otherworldly reward - but because it is the right thing to do.
