Same for Reverse Racism, Misandry, Etc.

Transphobia is the systematic dehumanization of trans people. This includes but is not limited to denial of medical treatment(not just transitioning), violence & rape & murder with no consequences for the perpetrator, discrimination in the workplace(including denial of jobs simply because someone is trans), discrimination against trans customers, etc. etc.

""Cisphobia"" is the disdain trans people have against cis people for being terrible to them and/or contributing to the systematic dehumanization of trans people. This usually is something along the lines of a trans person saying 'cis people are so annoying' on their personal blog. Trans people have no power over cis people so statements like this hold no weight.

If you want to stop experiencing ""cisphobia"", go back to reddit or turn off your computer. Tah dah, no more ""cisphobia""!
If a trans person wants to stop experiencing transphobia then they're out of luck.
