Correct. No leftist will ever lose an argument, although many will simply walk away in midstream when they see the handwriting getting scrawled on the wall.
Yes. A Leftist will often not even try to make any attempt at a reasoned argument. They simply state their opinion and think they’ve won. If you engage and say, “Here’s why I believe the things that I believe ...”, the Leftist will tend to give up and say, “You just won’t listen to reason” and walk away. And they will tell their friends that they won.
Walking away, sometimes abruptly, especially on certain subjects, is becoming all the more common.
