Why would you want to?
Seriously, I don’t care if you are liberal, but honestly if I know your political affiliation because you feel you need to tell me within the first minute of talking, unless we are at a political event, I am not want to anything to do with you, whether your political affiliation is left or right...
If you define yourself primarily by your politics, you hold no interest to me.
I was in my twenties and early thirties and if they had a good body I didn’t care how much what they were saying except that I could use it to my advantage.
Once they spouted something leftist I knew I was in.
