I don’t know much about this Sam guy but he seems to be converting both Muslims and Prottys. The handful of videos I’ve watched were good apologetics. I’m sure he’s not infallible but neither are the Diamonds. Sam is a former Muslim so that’s his expertise.
I’m not going to watch the video because it’s not worth my time. the diamonds love to sling mud just like they are accusing Sam of doing. I think both are trying to do good things.
