I agree with your point and Speed's about fighting discrimination with discrimination. I can't fathom why people would try to combat negativity with negativity that only hurts their cause. xD I hate the term "cishet" myself. Plus it looks like the sh should make a regular sh sound. I know it was created out of malice and is used in such a way. I've seen it on DeviantART and I (figuratively) ran screaming. xD I can imagine parts of tumblr would fester with it as well. It's so illogical that it hurts my brain. xD

1. Let's shout at the people who already have a misguided opinion of us to make them MORE misguided!
2. Catastrophe ensues.

Unfortunately that's the attitude of many groups, espeeeecially in social media.
