Haha. Believe me, I’m definitely not useful to the socialist left. I would say, though, that in the way you bear out their racist stereotypes of conservatives, that you are very useful to them.
You and I seem to have different motivations. My goal is to try and reach those who share values with Conservatism and then bring them over to our side. You seem to believe that this is not possible and that these folks should be given up on. The latter is not a winning strategy.
OK, since I don't have a winning strategy, suppose you point out the successes of your strategy in turning Americans away from Socialism.
You can start around 1900 when European Marxists first began sending Socialist political agitators to America and list your negotiated and bipartisan agreements where conservative policy was advanced, particularly when working WITH Socialists and work on up to present day.
It won't take long for you to realize how Useful you really are.
