I am not Femme (lol obviously) but I try to be an ally by:
1. Being a good listener. I listen to what they have to say and try to see things from their perspective.
2. Respect their points of view and accept that they know themselves better than I ever could.
3. Don't make assumptions about someone just because they self-identify as Femme.
4. Keep in mind that there are as many ways to be Femme as there are Femmes. Any one way isn't any better than another. It's just different.
5. Respect the rights of Femmes to have their own spaces and not try to invade theirs.
6. Speak up when someone says something bigoted or sexist or ignorant or rude about Femmes or to a Femme.
P.S. I hope it's okay that I posted here even though it is the Femme Zone. If not, I apologize.
