Why do today's Christians never express any kind of criticism against other religions?

I've been listening to local and far-away Christian radio stations for a long time. What strikes me is that, not even once, have I heard them (any of them) say a single word that could in any way be interpreted as criticism in any manner against Jews, Muslims, etc. If anything, they are very eager to speak about the "people of Israel", etc., in very positive wording, almost as if they were speaking about themselves. There seems to be no question to them whatsoever about the question whether Jesus was a Jew or not; as far as they are concerned, this is 100% established, and not a contradiction in any way. Maybe there is some kind of Christian branch which *does* have such criticism, but if they exist, I have certainly never been able to find them. And I suspect that they must have a very small following/reach if such is the case. But how can this be? One would assume that they would be talking about how the other religions are wrong and theirs is right, but... nope. I almost get the feeling that they actually consider themselves to be Jews, only with a slightly different view on some things. Even just the fact that the Old Testament is the basis of Christianity (expanded with the New Testament) is very strange to me since it only talks about Jews and not Christians. "Back in the day", I get the feeling that they had a quite different perspective. What has happened in recent decades?
