Yes, it’s “prejudging”.
I prejudge people who drop the n-word in casual conversation.
I prejudge people who use terms like "SJW" or "woke".
And, yes, I prejudge people who use "main stream media".
You can call them scumbag media, billionaire media, or tool of the warmongers media; but pre-judging people who use the term "main stream media" means you have chosen the side of the opulent oppressor, and willingly put up a wall of ignorance for yourself. Seems dumb, especially on a thread discussing this story of all stories.
Big fan of Chomsky, but his usage of the term mainstream media is not what that term has been co-opted to mean by some of the various forces he has, and is, warning us about.
'Socialism', 'liberal', 'terrorist', 'torture', etc... Allowing brainwashed loons and their puppeteers to decide what words mean is a mug's game, and I suggest you stop playing.
Your argument is "you don't know me", so I think we can end this chat there.
