My experience with the left is that talking makes them think that I am somehow in agreement with their values and they see it as a reason to impose on me.
Other than beating them to a pulp, how do you get them to understand that I don’t agree with them?
‘’How do you get them to understand that I don’t agree with them?’’
You solve it by applying the first part of the answer to your question to the second part.
I don't argue with them. I don't speak to them. I don't listen to them. I don't acknowledge their existence. Simply stated, I cut every single one of them out of my life. A few were dear friends for a very long time (20+ years.)
Any time I find myself in the same place/room/situation with them, I simply turn my back and refuse to acknowledge them. I really don't give a damn' if they know why I refuse to acknowledge them or not. If they're truly that damn' stupid I really don't want them in my life.
IMHO, the tipping point was when the leftists acquired the power to control people's thoughts (Don't say Merry Christmas, Thomas Jefferson was racist and should be shunned, do NOT share thoughts about election fraud, don't believe your lying eyes, etc, etc, etc). What is saddest is that the left has used 12.7% of our population to cannibalize all of the population.
It’s actually quite easy. You start preaching the gospel to them with the special emphasis of them going to hell where they will be ruled over by a power that does not love them rather than spend eternity in heaven with a god Who loves them, cares about them, created them.
