I'm always arguing with my father, but I'm afraid to be outspoken with my prospective husband?

My father is my father, but he's also a bit of a bigot and I always find myself arguing against his biased viewpoints. But he thinks that I need to be set in my place. I want to be more demure and less fiery when I have a husband because I honestly feel bad about arguing (debating is different tho). How can I be more subtle and ladylike?
