Today I learned that many people posting here are transphobic.

96. There is a difference between slipping in conversation -

where there is give and take and no inherent chance to easily stop the tongue before the gender you've used for years slips out. A friend of mine tolerated her friends slipping with pronouns for as long as they had known her as a male. Most didn't need that long - but it is an acknowledgement that it is sometimes hard to instantly switch.

But when you are posting on the internet (especially with forever-editing, and especially as a response to a letter which expressly requested that she be referred to using female pronouns), there is no excuse to get gender wrong. I'll be more tolerant with slips like using transgender as a noun, or adding "ed" to the end. Those kinds of slips are part of getting used to a new concept -and might even require some research if you don't happen to stumble across a recent explanation of preferences.
