Notice the christian never says, yeah, jesus is a jew, but x y z (ridiculous fictions presented as fact). Instead it always resorts to lying that he wasnt - thereby breaking its own proclaimed and posted commandment.
Never in my life, which has involved much contention with mental cross darkies, have I seen one troubled in the slightest by lying, and i mean with very little provocation. Christianity is not for people interested in the truth it's for people who want groupthink fantasy because it makes them feel good.
