I edited to remove this, because it detracts from the point, despite the fact that the Supreme Court has specifically ruled that ALL hate speech legislation in the U.S. is unconstitutional.
Whether or not "nothing of value was lost" depends on how much you value the freedom of Iranians.
Personally, I only downvote content that violates the rules or is spam. Since a downvote is the first step to having content hidden, downvoting things just because you disagree with them makes you a censor. That's not a good thing to be, yet the companies offering downvotes know about and encourage this behavior. Don't you ever wonder why? State actors routinely use these tools to silence their critics, and yet you play ball.
