I don't mourn the death of George Floyd either, because I didn't know him personally, but I was angry that he was murdered. It's not OK for cops to murder people.

And while it's true that there are some people who are using Floyd's death as an excuse to profit (certainly, people who are looting stores and stealing jewelry or sneakers are doing that), there are many people who are sincerely troubled, peacefully protesting and trying to make a difference. It's not OK to mock these people and it's not OK to imply that someone's life doesn't matter due to his skin color. You can express an honest opinion while still being sensitive to other peoples' pain.
