As long as someone has a church building, a bible, and a cross, the left heathen creatures will believe Christianity is being forced upon them. They're very insecure sensitive creatures.
I have to admit, this has been one of the more confusing aspects of Athiests.
Athiests..... do not believe in G-d. More than just 'not believe', but reject the entire concept.
How can something that does not exist..... offend an Athiest? Do tooth fairies and easter bunnies also offend them? Do you hear them talk about how Santa Clause and the elves are being 'forced' on them? If they truly believe that G-d is just as mythical as elves, faries, and the like.... why is it they don't seem to have a problem with any other mythical things?
I'm convinced the answer is at some level deep inside, they must know that G-d, unlike elves and faries, is in fact real, and they hate that, and thus they lash out at those who love G-d.
I can't think of any other logical explanation. Can you?
