Is it possible to not realize your child is gay, even when ok with it?

We have friends and relatives who are gay. It is not a big deal at all. But I have this adult daughter who was anti-gay. I think she got it from the public school. Kids at public school were bullied for being gay and generally had to be in hiding or leave the school because it was so bad. In looking at colleges, there is an LGBTQ-friendly school that even had a major in studies for that that my own sister went to. When she toured and the tour guide talked about being gay and his studies and such, she was done. She wanted nothing more to do with it. I was unhappy with her and had a talk with her about it and made it clear that I will not tolerate bigotry and if she has it inside her, it can stay inside when she is around me.Now, she is an adult (21 yrs old). And I can see online pictures of her being pretty touchy feeling with another young woman. For Halloween, she dressed up as a male partner for this female person. She was a male farmer and her friend was a female farmer. There was no kissing, but there was a lot of touchy feely, in ways that my daughter never even did with other guys openly.You know, now that I type this, I wonder..because well, maybe she was so hateful and rejecting toward gay people because she was thinking she might be gay but rejecting it. And she was always so mean toward any girl she knew, which made little sense. She kept calling them sluts and claiming she did not want to be around them because of how they are.What do you think? Could I have just completely missed this? Because of her adament rejection of gay people, I never would have guessed. via /r/Parenting http://ift.tt/2lX23ch
