I’m not making a “bad faith argument.” I’m trying to fight the widespread misinformation that there are “checks and balances” within the executive branch. Where is Community Notes when you need it?

You weren't even making an argument, just a comment. Standard tactic (you have been called out on this before) to write a short, goading comment with no content.

If you want, you can attempt to clarify why you're asking the person you're replying to if they know what checks and balances are. We can all ready social study books and read wikipedia (https://en.wikipedia.org/wiki/Separation_of_powers_under_the...) and it seems unlikely the response to your question is going to differ much from the philosophy and practice described there.

Not sure where you got the "widespread misinformation about checks and balances in the executive branch", the C&B are across branches, nobody implied otherwise.

This is an article about laying off a group (18F), that was never established by Congress in the first place. So I think if someone invokes checks and balances here, it’s fair to enquire what they think checks and balances are.

Saying “hey, don’t you know what checks and balances are” seems ruder.
