Every single Rabbi I have ever talked to starts the conversation the same way.
They break down first what you hold evident, then they fill in the spaces with their views.
I’m not anti-semitic. It’s just something that people do when they want to convert you to their ways.
Or maybe it's more that they want to establish a distance -- to make it clear to you that you won't convert them.
Just as Christians often tell Jews where they think they went wrong, Jews do the same thing to Christians.
It may make you bristle if you're not used to it, but I don't think the rabbi overdoes it here.
Also, Judaism has been around for a long time and doesn't always give clear answers.
Sometimes the rabbi's real argument may be with other Jews.
