I'm proud of the woman you've become. I was so afraid you'd be a lesbian when you were growing up.
Can you tell me why were you afraid that I may be a lesbian?
I'm saying that I should be proud of my straight daughter, as opposed to having a lesbian one.
I'm happy that you are proud of me dad, but saying that I would have been a disappointment if I were a lesbian is something that a homophobic person would say. I'm sure that you are not homophobic, but I suggest that you speak with mom about how lesbian individuals and people that are member of the LGBT community have had it very tough to get where they are today, and how it is not right to the ashamed of them.
