I've never had a trans person come up and tell me I'm wrong for being cisgender, or that I should change, or that cisgender people are just confused, or that they are barring cisgender people from using the bathroom. I have never had my cis life limited by a transgender person in my life, I am just allowed to get on with things with no harassment. Being cis is pretty chill.
Extending that same courtesy back to transgender people is not hard.
