Why is language so important to gender-confirming communication?

Have you ever been misgendered? Have you ever misgendered someone? You do not have to provide an example, but do ruminate on the power of language to explain how we do gender, create worlds, power inequity, and hierarchy  through the use of gendered language.

Another word for he/man language is androcentric language. Can you provide an example of this?

Provide an example (not from the book) of marked language.

Finally, while we still have a long way to go, do you think that it is possible that we can make positive changes toward less violent language?
