Well, 1st the "free speach/anti-hate/anti-racism" rallies are not being upstanding and they don't want to hear other points of views. This wasn't one of those rallies.

In the article and video, Newsome admits that his only goal was to disrupt and not listen. He was given the opportunity to say a few things and try to paint himself differently than the other leaders in BLM. He might have succeeded in doing so, but he didn't change the overall view of the BLM. Because, in the end, it was the pro-Trump organizer who stood out and offered the platform in the first place, even against the advice of another organizer with his group. At the end of the video, he talks about how surprised he was by how the militia leader and the pro-Trump leaders treated him so kindly.

What will be more interesting, is to see what happens to Newsome after this. He said "All lives matter", which BLM did not want people to say. They claimed it was an insult to their movement.

I think Newsome got red pilled and maybe it will change his local group, but I don't think it will change the larger group, because there are other forces involved that want BLM to be violent.
