You'll never find two human beings who are completely the same. Never, no matter how hard you try, you won't. I can assure you that.
There's diversity among us, we all are different somehow. Whether it's the color of our skin, our nationality, our preferences, our sexuality, our gender identity, our surroundings, our appearence... we are different from each other. And it's okay. As long as you're not causing damage to others by that, there's nothing wrong with it.
The problem is that we tend not to respect that diverstity, we tend to think of diverstity as something which is wrong. Even though we say we don't think that or that we don't care about diversity, are you sure it is respected? I don't think so.
I'll give you an example. Let's imagine a 10th grade classroom, with about 30 students. They're different from each other, but they act in a similar way, most of them. Nevertheless, let's suppose that there are like three students who are "different" or that's what they classmates do. One of those three students has a different sexuality than most of their classmates, openly. Other one is from another country, and the reaction of his/her classmates is the same as with the other kid. The third one doesn't like the same things as his/her classmates, has different hobbies, mentality and dresses differently.
The reaction of their classmates towards them is the same: the three teens are being teased, being made fun of, being left out... being bullied. Just because they're not like them. The three teens aren't causing any damage to the rest, but they're different. And that's what always happens, every day, everywhere.
Is it right? No. People say that we've become more advanced, and we have, but not enough. There is still a lot of discrimination to many people, and it's unfair - this must change.
Wouldn't you like to feel free to be yourself in public without hiding who you truly are? Wouldn't that be better for each one of us? What do you prefer: stopping hate and becoming acceptive, or living divided and hidden?
It's owned by us, only we can change that.
