Humanity requires some tough love. It might make it a bit easier when you learn to see not all included in humanity as necessarily human. Even when there is no real physical distinction, I prefer to make -at an intellectual level- the distinction between humans and what I see as Cro-Mags. They closely resemble the others but are not quite the same breed. So I reserve my love for the more deserving kind. The others are, at best, seen as a field-trip to the zoo.
I can't comment upon your video as I have never seen it but no matter what view you give in that plebeian zone called youtube, it is going to be responded to viciously at times. A very interesting function might be to disable the comment section. People can still mail you their views but the average Cro-Mag finds that already a too hard task so you'll already select against those. Another thing you have to keep in mind is why you are doing it. And this very purpose of it requires you to think about an approach that works best. I have no idea about your personal reasons to do so, so you are on your own. Just remember you are maybe only sharing views with a specific target group in mind, so the Cro-Mags flinging their intellectual or emotional excrements at you might be a small price to pay. After all, monkeys are as monkeys do.
