* You can support Trump, it doesn't mean other people don't have the right to think you're a moron, bigot, or supporter of fascism for doing so. You go right ahead and think the same thing about them. NO ONE ACTUALLY CARES. Most people are too busy working to get caught up in politics.
* Diversity of thought often comes with diversity of skin color because people with different skin color have a hell of a different experience than white people. They even have different experiences among their different ethnicities. Does it mean white people can't have different thoughts? No, but when you're in a bubble how would you even know?
* The way the H1-B is written now is terrible both to the H1-B holder and American workers. It forces workers to get paid below what they should get paid both as an H1-B worker and as the American worker. H1-B holders should not require sponsoring by a company. If their skills are in such high demand they should have no problem getting a job.
* If they could afford to sell. If they were stupid. Maybe they are optimists? Seems like San Fran has a ton of optimists. Maybe they plan on selling before sea levels rise or trust their government to bail them out.
* If this was all he said, sure, there's room for conversation about how and why we got into this situation, but it was a stupid screed against diversity. This guy is no champion of discourse. I doubt you could do what he did anywhere and have it go over well. You keep your politics out of your work whenever possible and speak your mind at home. A company is not a free speech zone.
* Equality of treatment doesn't mean equality of outcomes. That's a strawman argument.
