He’s clearly become unstable. He also likes to ping people who aren’t involved in the thread.
He passed unstable a long time ago. When he’s not insulting everyone as “LIARS !” for not viewing the world and facts the same way as he sees them, he goes on those diatribes. He must think we’re all hanging on his every long-winded harangue. I don’t bother reading or replying to most of the nonsense. Add to that, he outed himself as a Socialist when he denounced individuals that had to save their countries from open Communist evil, as if he should be seen as heroic for standing with Allende or the Communist Spanish Republicans. Total derangement.
As you pointed out, too, he openly disregards the request of others to stop pinging them long after they’ve disengaged. Pretty much just your quintessential globalist-Marxist troll.
