Jews generally have no problem with yeshu. They just wish his followers would stop (a) telling them he's their messiah and (b) blaming them for his death.
It's difficult when one religion is a "universal" religion and the other is not. I think that will always be an issue to some degree as far as tensions are concerned, but I think the moderators of this forum are doing a good job of keeping tensions down to a minimum and most people are here to work together, not against one another. Most Christians who come here haven't come here to cause problems or strife.
We have common interests with Jews in the current political climate especially, and true Christians will respect Jews because otehrwise we would never have had the Bible to begin with.
There is a history of some fanatics in the past during the Dark Ages in Europe acting like Muslims are behaving in the current time instead of being peaceful. Thankfully I believe most Christians today are more civilized than most Muslims and would never go back to that.
As for B, well, that never made any sense to me as Christian philosophy puts the blame on all humanity, not just one nationality. I've never seen the hatred by these virulent anti-Semites also directed toward Romans as well, so it's really ridiculous on its face. Those people need to grow up if they're still spouting that hateful stuff that doesn't help any group of people and can only hurt.
