I don't care what words you choose to be deemed offensive, but I do not ever recall giving you people permission to call me a "cisgendered person".
You say that using this word or that word is wrong because you find it offensive. Well, by that same logic, I declare that I find the word "cis", when used in context of made-up nonsense like "cis-het" or "cis-woman" or "cis het woman", offensive as hell so my intelligence feels very attacked when you use it. Therefore, you stop throwing those words at me effective immediately.
Anyone who calls me a "cis-het woman" will be banned from the website with prejudice. Those who do that in a context that has NOTHING to do with gender studies will be banned with extreme prejudice. Got that? Good.
