All these posts really belong on the 2020 election thread.
All of them?
You and your interlocutors have both made some reasonable points in your discussion of Biden's selection of a candidate for vice president. But I question the utility of making the same points over and over again.
How about subjecting each post to this test: "Am I preparing to say something here that I haven't, at least in substance, said before?"
If you're really trying to persuade others, rather than just indulge yourself, more time spent framing new arguments and less on repeating old ones is a good trade-off. Quantity is not quality.
