I'm going to reject him because of his culture/religion
Not a fan of his values?
I am not into the traditional thing. I feel it is outdated.
That's pretty much the entire reason we date. It's to find out who we are and aren't compatible with. I think you're being reasonable.
What do you mean? I shouldn't judge by traditions and culture?
No, I am saying you have the right to live by your own values. IF you find his regressive you can end the relationship and find someone who thinks the same way you do.
