Respectfully, I disagree.
I couldn't live in the house with a man who thinks a world leader who says 'Grab 'em by the pussy', and boasts about perving on young girls in changing rooms, is even remotely appropriate, especially as I have a young daughter living here. We're not talking about a comedian who made a distasteful joke, we're talking about the leader of one of the most influential countries in the world.
Agree to disagree is an important skill to learn, absolutely. However, in my opinion, not for this. My husband is free to have whatever opinion he wants, but his opinions don't always come with freedom of consequence. The consequence being, I would no longer wish to be married to him. I think quite the opposite to you, I believe that this would be teaching my children how to have successful relationships. They would be learning that you don't have to compromise on your morals just because you love someone. I chose to be with my husband, I can chose not to be if I wish.
I actually had this conversation with my husband earlier, although I was pretty sure in advance what his answer would be. He felt exactly the same as me, that if I started supporting Trump and saying he was great, he wouldn't want to be married to me either, because he feels we'd be so fundamentally mismatched. So no red flags from his perspective!
You can call it controlling if you wish, although I disagree. I'm not saying he can't have those opinions (that would be controlling), just that I could no longer be with him if he did, but he is his own person, he can exist without me. You can also say you think people like me haven't grown up since the common room, entirely your opinion. I don't understand why staying with someone when I don't want to would make me grown up, but oh well.
