I know your English is non-native, so I understand you were not trying to be offensive, but that phrase would be better rendered as "Jewish cousins."
But I understand your main points and agree with you. We should not be surrendering our culture or habits to Muslim invaders. They should assimilate to our culture or go home. I think Jews are not a problem in this regard -- they assimilate into the culture and are, for the most part, patriotic citizens of their country.
If a Jew were mistakenly given pork, it would be accepted as a mistake and forgotten. There would be no violence, no jihad. You should not equate the two peoples, Muslim and Jew. There really is little comparison.
Well said.
