Not to be a prude, (just for the record, i am not part of an organised religion).
But the reason why people make such a big deal out of this whole thing is because bringing religion into it was a stupid move, and uncalled for; with potentially dangerous repercussions.
And to answer your question, theliverevolution, about why no one would think the same if it was another religion; people WOULD definitely not like having religious ideas inapplicable to theirs forced down their throats.
Furthermore, a minority of Christians tend to be the preachy convert-to-christianity-now-or-forever-be-damned type, and because of these few people, they have crafted a stereotype of themselves for Non-Christians looking in from the outside, or have been subject to their activities.
Not to say that there aren't preachy Buddhist, Hindu, and Muslim pricks too, but the Christians have just been more...conspicuous.
Just my two cents,
Please don't sue.
