This is a broad question, but here is my experience with someone on the other end of the political spectrum. We were coworkers for a few weeks. I found out that they aligned themselved with the alt right party in my country, and it bothered me a lot. But with help I also realized that they weren’t dangerous and mostly frustrated by german politics - fair! - and willfully uninformed.

On the last day we worked together I mentioned that I was really nervous/upset about an appointment I had in the afternoon, and they were caring. As I left work they wished me the best for the appointment. This is the last impression I had of them and I found that really sweet. People are more than their political beliefs. We may not subscribe to everything they think is right, but I find that as long as it actively doesn’t harm us to be kind, we should be. Avoiding someone and being upset also takes energy.

And I believe the individual needs understanding and compassion when discussing politics. As long as the person isn’t a threat to others, and as long as you find their company neutral or even good, I think this is the way to go.
