The liberal debating tactics. I coined that phrase specifically to describe what I was seeing, though I'm sure someone used it before me. I googled it and see the phrase being used, but I don't see that anyone has specifically tried to define it yet. Maybe we should try. Most of it is seen in politics today, the creating false narratives, etc.. Victimhood is a major tool used to manipulate people. Stuff like that. Here's a couple of that I would call liberal debating tactics.
1) Attacking the person, instead of dealing with the point made by that person. While noting a questionable character is expected, usually the substance behind their questioning the person is false and was created by the same people. In other words, where there is smoke, there's fire, says the person creating all the smoke.
2) Continually boasting about how easily your point is refuted, and how it has been refuted many many times in the past. Just a constant belittling, while offering very little to actually refute the point that they are confronting. This tactic is used to add emphasis and profoundness to a short reply that wouldn't otherwise have either. In short, It's an argument made for itching ears and simple minded people.
