No, it's more about Elsa's ice powers being interpreted as a metaphor for homosexuality (girl is forced to conceal and taught to fear an essential part of her identity, which makes her miserable; it's only when she learns to love and accept that part of herself as an adult that she finds inner peace) and "Let It Go" being seen as a coming-out anthem.

Well, it is a Disney movie, and one could just as easily headcanon her as asexual. :P
