Stop enabling them on a personal level. When they come to you for help, decline. When they come to you for assistance, decline.
Seems to me that since we are routinely characterized as idiots, morons, neanderthals, etc, how in good conscience can we come to their assist? If anything, we would be more likely to cause them harm rather than help them.
Let them fend for themselves and ultimately take some lumps. I maintain that the average liberal benefits more for their relationships with conservatives, than the average conservative benefits from their relationships with liberals.
Try it - it's fun.
Isn't that the truth !
