I don't think that Sam is muddying the waters anymore than they already are. These are muddy waters, they always have been and always will be.

All ideas have consequences, but no debate is completely rationale. We need to be ok with that.

"Hey Joe, let's hear why you think slavery is a good idea. What's your reasoning?" At the very least, Joe is going to walk away with the realization that his rationale isn't very persuasive. He'll probably also realize that his views make people doubt his moral character. He's going to have to chew on that. However, if we just say "Shut up Joe. Slavery is wrong, we all know that. Get lost, asshole." Joe is not going to have a constructive takeaway that diminishes his convictions.

Joe is ignorant. Sam is ignorant. We are all ignorant.

Sam isn't making the world worse by not having a moral litmus test for funding startups. Sam funds startups. That's his vocation. Being a misogynistic racist manchild didn't stop Donald Trump from getting real estate loans. It shouldn't.

BTW, it's been a while since we've had a good 0-share long discussion post. :)
