I've been misanthropic for at least 15-20 years, since I was 30 or 35.

But I think there are both good and bad arguments used to support it. Something I've noticed is that one of the most common bad arguments has to do with the assertion that one part of a complex relationship or reality is the only part of that relationship/reality.

If you had beef, beans, onions, peppers, chili powder and other ingredients in your bowl of chili, it would be a fallacy to say that the chili was nothing more than onion, right??

Yet, some misanthropes argue just like that. They observe complex relationships which seem to include love, hate, hope, fear, happiness, sadness, altruism, selfishness, silliness, seriousness, and a thousand other feelings and define those relationships only in terms of the negative qualities. For example, it will often be said that relationships are only ever selfish, that everyone is using each other, thereby selectively ignoring anything that is positive. Whatever is positive, like kindness, is then said to be nothing more than greed, selfishness, and so on.

Why not admit that humans are complex, with both good and bad traits? Reducing all the good traits into bad ones is no better than an optimist looking at the bad ones, like hate, and saying that hate is really another version of love. It's illogical.
