The sad thing is that they just make themselves look foolish and they make Christianity look foolish as its representatives. The media plays on these stereotypes for all it's worth.
I never realized my belief in God and his word was an embarrassment to Christianity. Somehow tho, I don't think that Jesus is embarrassed that I believe the word of God is truth.
However I believe some people may be confounded by their pride in being more enlightened than the ignorant masses who actually believe in the Bible.
You are confusing believing in God and the Bible with idolizing a book and interpreting everything in it literally without thinking.
It is. Chr*stianity doesn't want people like you or me. Believe me, I've been there, and it ain't just the Catholic Church, pal. All the ancient churches are redneck-bashers.
I advise you to at least consider the claims of Torah. And among traditional Orthodox Jews and Noachides you won't find yourself an embarrassment at all.
