The term evangelical, as I believe I typed before, just means "born again". In a culture where the default is "Christian"--which means, "I'm not Muslim, Pagan, Jewish, Hindu or Buddhist, so I guess I'm Christian cause I like Christmas" it defines us as being devout about it. We're not just cultural.
The Bible is full of examples wherein Jesus Himself withdrew from sharing His teaching, or asked people not to tell what happened. Similarly, the disciples showed great discernment about when and who to share with. The "Good News" is always an invitation to be accepted or rejected. Always. And it should be approached as such, so before a Christian even extends the invitation...you get a "feel" for whether the person is receptive. It should never be a sledgehammer. Or even close.
We have no particular calling to "strip" Jews of their faith. I would be honest about this: I have never read nor heard nor encountered such a thing. We don't think of attempting to "strip" people of faith. We think of introducing them to Jesus. That's it. See above: accepting or rejecting.
