Your personal experience is that you think Jimmy Dore has some sort of positive impact on leftist discourse or exposure and shouldn't be disregarded out of hand.

That's fine, that's an opinion, and I'm sure people would be interested to hear you out on it.

The rest was your guess at other people's personal experiences and painting your opinion as the "Black-approved" one, which is then equated with the correct leftist view.

We see that tactic all the time when white liberals defend Bill Clinton.
