To be honest with you, I stopped dating gay men that far left. I also find they're the ones who are actively promoting this idea of "oppression" in almost every area of human nature that I disagree with. In other words, they think everything in life is the result of being a social construct, therefore most of everything is interchangeable or fluid. The typical "capitalism is evil and you should hate it to" type of dude. They pretty much stand for most social systems that I don't like.

Most people would advise that you don't introduce politics into your dating life, but I only agree with that if you have two people who aren't very political to begin with. To give an analogy, it would be like taking somebody who's an atheist and sticking them in a relationship with a highly devoted Christian. It's possible that it could work out in the end (I'm sure it does for some after compromise), but for the most part, they're going to realize the very fabric of their social structure and beliefs conflict, therefore there is going to be tension there that will eventually erode the relationship unless they accept these differences and move on with their lives.

At this point, I tend to date moderate and Republican men unless they're religious. Moderate men come with their own cons, but I tend to find more in common with them than I do with somebody who falls very far left.

Dating itself is a pretty poop process, but introducing politics and religions into the mix makes it a bit more complex. It really is going to come down to how important your political believes are in your lives, and how you can meet in the middle to make that work. If his positions are already making you feel a bit tense, then I would take that as a sign the future might be a bit rocky unless you both talk about it and work it through.
