Could be. Especially if they don't read much of posts. In my experience, as I have participated, I've observed some things: 1. A lot of the people who join in here like to have fun: Many remain capable of placing tongue firmly in cheek, even use sarcasm. 2. A lot of the people who join in here know a lot about something relevant, but that doesn't stop them from learning from others 3. Most of the time everyone seems tolerant of everyone else, even when we disagree (or pretend to disagree for sport)

Underlying the entertaining bits, of course, are some serious subjects. And one way to detect "credible" is by challenging with questions. When the response is "the science is settled" or otherwise dismissive of inquiry, you have found a non-credible source.

Most people on this forum seem able and willing to both ask, and consider, challenging questions. Leaders of the CDC, The Media and The Party, not so much.
