Misanthropy and Veganism
Upon becoming disillusioned to the cruelties humans inflict upon animals every day by the millions, and every year by the billions, and witnessing the general populace's apathy to their plight since it's in the latter's benefit, it is very easy and very common for a person who has just recently gone Vegan to take on misanthropic views, ones that view the human species with nothing with contempt and scorn.
While at first it's completely understandable to take on this sort of mindset to view human beings as nothing but immoral parasites who do nothing but wreak havoc on animals and the planet, but this mindset is not only irrational, immoral, and incorrect, when it is associated with Veganism, it causes huge amounts of harm to the animal rights movement.
If even after all that reasoning explaining why misanthropy is a naive and idiotic worldview you still insist on hating humanity with a burning passion (which in your case trumps any sense), all we ask is that you keep these misanthropic views to yourself. We do not care how strongly you believe them, we do not care how right and justified you think you are in holding these views, and we do not care if you think more Vegans should take on a similar mindset. The fact of the matter is, misanthropy is viewed as an abhorrent worldview by society at large, and society at large is who we need to reach in order to get the world off of animal agriculture. If you put off society from Veganism because you're associating it with such a view, you are making it significantly harder to reach them in order for them to cut down or even eliminate their consumption of animal products, and this is something that really hurts animals. That's what we DO care about;
Case in point, retired animal rights activist Gary Yourofsky. Instead of retreading all of the problems with Gary, it is important to explain how misanthropy can cause an effective Vegan activist to lose their way.
Near the end, it was hard to tell if it was still about the animals, or if it started becoming less about them, and more about his narcissistic hatred of humanity. While Gary's activism had some flaws, particularly in his use of bad arguments (e.g. gross-out, humans are herbivores, etc.), opposition to animal welfare laws, his unwillingness to acknowledge any sort of moral gradience (i.e. a being is either in the circle of compassion or is not), his speeches have been massively impactful, and are credited with converting tens of thousands to Veganism, as well as inspiring hundreds to get into Vegan activism. However, along with all that came his extreme and uncompromising misanthropic views, which were expressed with hyperbole (e.g. "...we are the nastiest, filthiest, deadliest parasitic-organisms to ever infect The Universe!").
Did Gary really not consider for a second that these views do not portray Vegans in a negative light, and thus would push potential vegans away from considering reducing or eliminating their consumption of animal products, and hurt more animals in the long run? Or did he just not care? If the former, that would make Gary either suspiciously injudicious, or (and the probably more likely answer, if the former is accepted as the explanation for his behavior), just very, very stupid. If the latter, then that means (at least after he became a big name in the animal rights movement and gained a large following) he stopped doing the activism to help animals, and more just because he wanted to boast about how much he hated humans, and used the abuse humans enforce upon animals as a sort of leverage to justify and reinforce it.
