<human>: The title pretty much sums it up. I imagine this situation arose from television. 

My mother is a 65-yo old-fashioned Catholic woman who constantly has <redacted channel> on. There's daytime shows that have transgender entertainers and the rest is probably history. 

I hadn't approached sexuality with my daughter yet as she is 5. I want my daughter to know there is more to being gay than a "boy wanting to be a girl" which is an atrocious explanation. 

My sister is gay, and she has had to deal with the discrimination her whole life. I don't want my daughter unknowingly upsetting her. How do I fix this?

Can you give me the gist of the text in a nutshell?
<bot>: My mom told my 5yo that gay people are "boys that want to be girls." I want my daughter to be more open-minded than that ridiculous definition. What do?
