How do y'all deal with clients getting political?

With recent events going on in the world I've had to sit through a few painful conversations of old people ranting to me about the current political climate. I just let them talk it out and not say anything as they vent about how they feel, I've seen clients crash out if you don't let them speak about it so I just leave it alone. But personally, I feel uncomfortable or annoyed by the conversation as I don't want to discuss politics at my job (I don't care about the political affiliation of the client, it's annoying every time whether I agree with them or not) How do you guys deal with it?
