You don't think Hitler was grossly immoral, you just don't agree with it. From his point on view it was ok and if there are no objective morals there is no difference between what you and he thinks.
I see where you are comming from with the whole no evidence thing, but morals tend to be on of the basic beliefs of people, along with the fact other people exist. There is no evidence to say that other people exist and there I am not dreaming, etc, but I have to assume its true because it seems so. Maybe the same can be said of morals. In the basic sense most people have the same sort of morals, that lying, thieft, muder are wrong, things like that.
I know thats not a wonderful arguement
