I've started to realise cis people really don't know anything huh

When I came out to my mom and was trying to explain dysphpria I was a little stumped bc I wasn't getting anywhere at first she just kept thinking oh its the same as people who wish they were taller and i was like uh no and then was also confused on why someome would want to be a women or why can't they just stay the same. And then later as I researched more I'm starting to think damn cis people really don't know much do they like at all about us.
