I don't want my wife to talk politics with me anymore.
Why don't you enjoy talking politics with your wife?
I don't want to discuss that with her, since she already gets on my nerves.
Politics can be a sore subject with some I agree, but everyone has a right to their opinions. You have to remember though to not be bossy with your spouse, she will be resentful towards you and want to scream. If the talk gets out of hand then leave the room.
I don't care what other people think, she should listen to me. I am the man in the relationship.
It's not okay to expect your wife to agree with your political views just because you're a man. Everyone has the right to their own opinion. If it leads to arguments, you can stop talking about it, but you can't force her to change her mind.
