Seriously, people have always asked questions like, "Has he/she been blind since birth or did they become blind later".

In a lot of those articles you linked from Google, that seems to be the big reason why Elsa is gay.

What's sad is I was just thinking that it was nice that there's finally a Disney princess who isn't already paired up with her prince.

I do agree that the film could be used for gay people to identify with Elsa's repression, but that doesn't mean she's gay. Just like many can see strong Christian values, LGBTs can see their own values shown. That's an example of a good movie, it can touch many people in many different ways.
