Because people should have the same rights, regardless of any superficial physical discrepancies like skin color or genitalia shape.
It may be a fact that everybody's all different in terms of strengths and weaknesses and qualities.Here's the real truth. No matter how much our qualities vary, every last one of us is human. We all belong to the same species. We all have common ground and a root at our core. There is no human out there that likewise, can't relate to another human in some way because we all share similar experiences.And, ultimately, no matter how good or bad you are, how rich or how poor, how smart or dumb, however sick or healthy, you are born. And you can't outrun death. Nobody can. We're all born, and we all die. Which means that all of us share a limited amount of time together. We're all equal in that regard. And as such, while we're alive, we should strive for an equal and level playing field for people as best we can. Assume that you only get one shot at your life.It wouldn't be, and it's not fair that your one chance is wasted or mired in bullshit in spite of bad dice rolls or even other people being cunts to you because they somehow believe they're above you, when at the end of everything, we all go anyway.We're not born equal but we sure as fuck equally die.
