[/color]No, you wouldn't. You would feel horribly burdened. You've made that abundantly clear.
Also, you are of the mind that "there is no difference between a Jew and a Gentile." So, what value is being a Jew to you?
It has no purpose, as you have stated. You get nothing out of the special covenant that God made with the Jews, involving a lot of various and sundry commandments that direct all aspects of life, ensuring that (when we do what we are supposed to) that our lives are lived in holiness.
You've made it clear you want no part in that.
Whatever.
No, not really. Good intentions are well and good, but you can also be self-deceived. (It's one of the countless Christian arguments that has been thrown at me over the years.)
Action has a lot to do with thinking and attitude. You can trust an action. Even if a good action is done for the wrong reason, good has still been done.
