A corollary: "Humanity" isn't perceived or granted on a binary basis. We can legally ordain anyone to be anything we like, but it doesn't necessarily translate to swaying all the ethically bankrupt -isms that are undeniably still floating around. These -isms most obnoxiously surface through anonymity; 4chan is racist and sexist past the point of absurdity. It reads like a politically incorrect "Tim and Eric" skit or "The Onion" style irony taken to the furthest possible extreme. Also, we are all literally wired to discriminate from eons of tribal lifestyle. When white people still dominate the political prowess of an entire nation (hell, much of the developed world), I think the result isn't really arguable. It's slowly getting better, but I know that I'd like to see total equality ASAP, and I have to work through my own inherent biases to do my part. It's not just race, the same goes for women's rights, LGBT, etc.
I do not mean to say that humanity doesn't discriminate, and I don't mean to say that that shouldn't be considered a bad thing. I mean that saying "we are treated as not human" implies a far worse treatment than stereotyping. I consider someone who is thought by society to be inhuman to have zero rights, not to be human outside of one right, or a few.
This is where I will take a rather binary stance in favor of idealism. The level of discrepancy between the ways different groups of people are treated is of no concern to me. That is exists at all is factual, and something to continually address and improve upon. I can see that you and I do not perceive it to be of the same severity, but like I said, the issue deserves acknowledgement and discussion.I mean that saying "we are treated as not human" implies a far worse treatment than stereotyping.
