[I want the USA back]

The Bible is longer than the kuran. Neither Christianity nor Judaism practices the things mentioned in the Bible. islam does the things in the kuran.
End of discussion.

Why the hell does the left want to trash Christianity and idealize islam?

[Yosemitest]

It's a SATANIC THING !
They LOATHE our Heavenly Father and His Son Jesus Christ.

I remember our Heavenly Father telling us HOW to handle other religions,
how to show the proper reaction to their false gods.

Read how"Elijah mocked them, and said,
Cry aloud: for he is a god;
either he is talking, or he is pursuing, or he is in a journey,
or peradventure he sleepeth, and must be awaked"

Also:

Bring out thy son, that he may die:
because he hath cast down the altar of Baal,
and because he hath cut down the grove that was by it.
And Joash said unto all that stood against him,
Will ye plead for Baal?
will ye save him?
he that will plead for him,
let him be put to death whilst it is yet morning:
if he be a god,
let him plead for himself,
because one hath cast down his altar.
Therefore on that day he called him Jerubbaal, saying,
Let Baal plead against him,
because he hath thrown down his altar. "

Here's a great example of responding to those followers of FALSE gods.
Jerubbaal and Joash of Judges 6 and Judges 7 are well worth your time.

I think this is the left’s attempt to denigrate ALL religion like Marx, Darwin, Freud, etc. Then the left can elevate a man to godhood (similar to Obama when he was first elected). This will be the antichrist (in place of Christ) savior they have always wanted...the Ubermensch!

Why the hell does the left want to trash Christianity and idealize islam?

Setting the whole Satanic verses aside, it's because they are fellow travelers. Christianity, and hence Christians, stands between both ideologies and what they want; control.
