When integrity and obedience collide...

Let me give an example:

Let's say your man wanted you to condemn feminists. (This probably wouldn't represent an internal conflict for most women posting in this subreddit, but bear with me.)

Or maybe a different example. Let's say he wanted you to say that the people of Group A were awful, malicious, dishonest people and you, yourself, couldn't see it. Let's say you were torn between following the directive to smear Group A or to follow your own conscience, which tells you that you shouldn't shmear a group of people without at least believing that what you would say is the truth.

When there's a conflict between doing what you think is right and doing what your partner thinks is right, what do you do? What should you do?
