How do you compromise with someone who doesn't even accept your values as valid or reasonable?
What kind of extremists are you in a relationship with?
Short of autism, there is no reason a standard Dem/Rep shouldn't get along. You're moderates with varying degrees of what constitutes proper immigration reform, taxes, public spending, etc.
I have never seen an antifag wife a wignat or a neo-nazi wife a tankie for one person to think their spouse's ideas are invalid or unreasonable. If you're that extreme, you've almost definitely already showcased your ideals to your partner and a split was announced immediately afterwards.
Compromise lets be real fucking sucks and if your whole realtionship is based on compromise then you are losing yourself.
You and I may have different concepts of compromise.
Compromise is listening to your husband drone on about X topic while you couldn't give a damn but smile and pretend to listen anyway. Compromise is wanting to stay at home and watch TV but your spouse wants you to accompany them outside to run errand somewhere. Compromise is knowing you can shut your wife's argument up but stay silent because it's less stressful than the alternative.
Compromise is not saying anything when Y political candidate is on TV and your spouse beams with glee about how right they are about everything. You won't care or get mad if you voted Trump but they rode with Biden.
Compromise is letting them choose the music for the ride home, even if what they'll pick is boring music, jogger anthems, or satanic edgelord cringe.
I've seen so many divorced couples who doomed themselves by refusing to compromise anything. Food, entertainment, political discussion, etc. If you want someone who agrees 24/7, stay single.
I don't see any of these compromises as radical or so far gone that you cease to be you just to please someone else.
And wanting a Yes-Man of a partner who parrots you and never doubts or challenges you gets old real fucking quick.
You saying right now that everyone is just an aimless peasant is a good example of something that could cause a schism in a relationship.
Let me try this again.
Don't get uncontrollably mad in the event your spouse doesn't think N political topic should be addressed in X or Y manner and thinks that the solution is Z. Politisperging is not worth losing someone over, considering that as far as federal elections go, your vote matters very little in this uniparty clown show we have going on right now.
Trump didn't save you, AOC is not going to save you, Bernie is a grifter, Cruz is only looking out for a future presidential run. It's not worth getting mad fighting over these people or the politics they represent. Focus instead on your local politics which I can guarantee affect your daily lives more and are probably a fusion of both your ideals and beliefs.
