Thank you for your post, but no where in the NT does it tell Christians to murder Jews. Hitler used the Lord in the same way that Charles Manson did: he manipulated the Lord's word to convince the "ignorant" (Biblically) to do his bidding. Being aware of the Lord and reading the Bible does not make you Christian. Accepting that you are a person and Yeshua is Lord, and that you need His love and mercy (genuinely, ask Him into your heart), is the only way that a person can become a Christian. Also, you can be a Christian and "choose" to turn away from Christ (in the NT, this is described as worse than not believing at all).
Ah, the "No True Scotsman" Fallacy...
Or you could say a wolf in sheep's clothing.....
