When I was growing up one of the virtues that was taught was the saying, "If you can't say something nice, don't say anything at all." As far as I know, this is still often taught to children as a guideline to behavior, yet from what I have witnessed of people lately few adults are following this advice themselves, especially when it comes to advocacy efforts.
Let me preface this by saying that I am aware that there is often a need to be outspoken, bold in order to be heard. Sometimes we have to be less than nice to take some of our power back, because that's how power imbalances work. No one group holding the most power, and privilege is going to relinquish it in a passive manner, because the oppressed is asking nicely. That's not how it works.
However, when did being a snarky, condescending, foul mouthed, angry person spitting sassy comebacks at everyone whom you cross paths with become what we call advocacy? When did answering every question from others from different groups with an air of, "I'd explain this to you, but you're just to stupid to understand it."
