@serrebi The problem with saying it goes both ways is that one way is significantly more harmful than the other. Cis people villainizing trans people can lead to restrictive laws, abuse, violence ... trans people speaking negatively of cis people can, at most, upset some cis person on the internet.

Not that comparing oppressions is ideal, but it is similar to us blind folks calling sighted people sighties, sightlings, or some other word du jour. Most of the time, that is done either jokingly, or when complaining about actual ableism against us, such as being talked to like a child, grabbed without permission, mocked, etc.

Can it get a little mean-spirited, sometimes? Sure. But it is our way of coping with actual discrimination. Pain is not always pretty; sometimes it is angry.

And far, far fewer people are actually committing violence against, or killing, blind people. Far fewer are not merely not acknowledging we exist, but openly, hatefully saying we should not. That's the trouble with comparing these things. But hopefully it makes the contrast clearer.
