It was online discussion so when I say "Others" I'm combining messages. I don't think there is a "true" leftists. There are the narcissists who quickly change their wording to take whatever will causes division. Many confuse those.

The "protect the unvaxxed" didn't last very long. He said that and they quickly agreed with whatever he said, then realized slowly what he said and didn't like that part. After that they guided him back to "unvaxxed are selfish".

It's more of a hive mind. One member of the hive says something that isn't in agreement with the hive thinking so they "agree" at first then coax him back to the correct thinking. It's subtle and unnoticed.

You see it all the time with them. If someone strongly rejects the hive-thinking he'll be pushed out, but if he said something by mistake that wasn't in agreement they'll agree at first and nudge him slowly back to what he should think.

Hive mind thinks: Coffee is racist.

Member of hive says, "We have to treat coffee the same as tea."

Hive mind goes, "That's true. You're right," then later comes back and gently says, "But tea and coffee aren't the same. Coffee is racist, you know."

Member falls in line and says, "Coffee is racist."

They only get harsh if you defy the Hive. If you just slipped up they'll guide you back slowly. You won't even notice.

So I'd say it wasn't the case of a moderate in the mix. It was more of he unknowingly said an idea that wasn't in line and they took their time to bring him back to the correct thinking."
