Question For Dispensationalists?

I don't mean to tar everyone with the same brush here, (so if you're a dispensationalist then feel free to exclude or include yourself in this), but I do see in the most part a large inconsistency amongst many.
Dispensationalists tend to subscribe to magazines about the glory of Israel, buy their oranges from Israel etc, give money to Israel, support any government that is pro-Israel, interpret most of Scripture as being about Israel, get very upset when anyone disagrees on Israel.

So my question to dispensationalists is:
When was the last time you witnessed to an ethnic Jew and how often do you do this?

To borrow a phrase from Voddie Baucham, "Don't say Amen you ought to say ouch".
