IMO its insulting .. as if Jesus isn't enough so we have to steal scripture.
I've met many Christians that I respect, even as I respectfully disagree with them. They are good people. They are not stupid. They are devoted to God and to loving others. But of course I have issues with the Christian faith. As I've said many times in here, I'm not here to convert any Christian away from Jesus.
But since you've brought it up yourself...
The one thing that bothers me the most is:
The way the New Testament either directly misquotes the Tanakh, quotes verses that don't exist, or hauls parts of verses completely out of context.
And the second is like unto it (pun intended):
The way Christians imagine messianic prophecies everywhere in the Tanakh when they are not there. It's like seeing castles in the clouds. You just can't stop them. They have Jesus imprinted on the glasses they look through. It's like Catholics seeing the Virgin on burnt toast.
Okay, I got it off my chest. I should go listen Tovia Singer for a while and get rid of this headache. I have walking pneumonia and I'm miserable. I'm still awake because I can't sleep since I can't breath. Thanks for keeping my mind off my achy head and scratchy throat.
