Sure, granted. That’s self-evident.
But I believe in the idea of a world where someone can walk around and not live in fear, or be subjected to bigotry, just because of their ancestry or sexual orientation. One of the few places I’m happy Canada’s speech laws are more restrictive than the US’s is right here with what you describe - a sign like that would be considered hate speech.
People believe what they choose to believe. Recent studies suggest that people make up their minds about each other mere seconds after meeting subconsciously anyway. But IMHO what separates us from the rest of the animal kingdom is our ability to choose to ignore our base instincts and instead act out of an abundance of consideration for others. And I choose to fight for, and promote, the world I would hope to see for everyone, free of such things.
It’s good to see that we’ve reached a point in the west where what happened in Indonesia can be considered “barbaric” by most. It sucks that there are parts of the world where this is not so. And it sucks that even in the most “enlightened” places in the world, people still need to fear discrimination for how they look or who (or how) they love. They are all important facts, both worthy of discussion and worthy of action against.
