Some of us have tried, but why should we? Denying our attraction to one sex or
the other HURTS. If you ask the question out of innocence (you don't feel this
attraction, so why should anybody?) then you're asking us to put away feelings
that we cannot and will not live without. If you ask these questions with full
knowledge of the issues at hand, then your question is as patently offensive
as a white supremacist asking us to choose one race over another.
