When you write "polyhacking", do you actually mean "bihacking"? If not, what you say you fear seems to me a very odd thing to fear.
Actually, I would be quite surprised if (within, let's say, the next 40 years, and assuming no huge technological changes that would affect this) heterosexuality + unwillingness to try to become bi were enough to get anyone widely labelled as homophobic. (I'm sure there are already people who would apply that label, but not enough to have much impact.)
[EDITED to add:] Just to clarify, the point of the second paragraph is that I find Val's fear not-terribly-plausible even if "bihacking" is what s/he meant.
You are right, I meant bihacking, my mistake.
My concern was based on the observation how the word phobia (especially in cases of homophobia and xenophobia) is increasingly applied to cases of mild dislike, or even to cases of failing to show open support.
