To understand why, you should simply ask yourself why you posted this exhortation to "give it up" to the give-it-up group.
As someone who also reads this list --as a member of the audience, the reader -- I've changed my way of thinking about various topics and gone back to reread material because of what people have written on this list or what they've said in discussions/debates.
Carrol and I've gone round and round over the years, for instance. I was completely opposed to most of his positions on party building, etc. having gotten burnt out on various kinds of activism. We still disagree sometimes on the issue, but it seems to me that we've both come to appreciate one another's position and even managed to alter our own because we've influenced one another on the topic. His arguments and explanation about the use of rhetoric, logical fallacy, etc. etc. have also been persuasive. I could probably list more people who've similarly influenced my thinking.
Thank dog people are muleheaded sometimes. I learn a lot because they are. E.g., I'm learning a load about exploitation and the labor theory of value as I read Justin, Woj, etc.
