As someone who is not on Twitter, what does Pelosi mean by adjusting settings? That tweet string does not explain it.

Thanks in advance.

If you do, any tweets that have sensitive content - cursing, etc., - won't show in your feed. But if you want to see everything, you just change your setting. This has nothing to do with censorship, other than self-censorehip.

In other words, McCarthy doesn't know he essentially put a parent control on himself.

Now I feel less stupid than McCarthy.

Never had an account, never intend to get one. Knowing how Twitter works is not a badge of honor - quite the contrary. If someone "mocked" me for not knowing how Twitter - or Facebook, for that matter - works, I would take it as a compliment, knowing it means I'm part of a small and seemingly ever decreasing elite who will not bargain with their integrity, sell their soul to advertisers, or feel the need to tell the world what they had for breakfast.

And is too lazy to find out something he consistently uses works, and predicates his criticisms on that ignorance.

Not too many people would ignorance and laziness as a compliment.

who was equally sure he was always right. He once (that I know of) dialed a wrong number, and was so sure it was the phone company getting it wrong that he kept hitting redial.

Kevin McCarthy hit redial on this confederation, when the correct response would have been to say oops and get out.
