I do know something about it, because I went and found out what the Jews expected of a Messiah.
I'm not going to accept Christian theology uncritically unlike many Christians.
Similarly, others aren't going to accept your interpretation of theology - how ever much you might have investigated it - uncritically. Especially when it doesn't ring true with what we have discovered in conversation and discussion with followers of whichever faith you have chosen to refer to.
Nor am I going to be intimidated by Christians who believe in their own theology more than anything else and who would like to silence me.
That isn't a problem, so long as you are happy to be challenged and questioned on your own understandings and claims.
Probably because they haven't been taught how to answer real questions.
It could possibly also be that they haven't been taught how to answer poor questions.
There is no reason why I should accept anyone's theology.
Not sure that anyone is suggesting that you have to.
Not all Christians accept all of each other's theology anyway.
Yet there are core doctrines that all Christians agree on.
