@sozobe,
A littttle rant, if you don't mind.
I see this issue come up a lot within my daughter's circle of friends (and acquaintances).
I'd love to see things get to the point at which
it doesn't matter, at all, and there's no particular reason for confusion. People don't agonize about whether they're attracted to redheads or brunettes, and then declare that preference and stick to it forever. People just go along and meet people and maybe they'll be attracted to a redhead at one point and a brunette at another.
Of course, right now, the issue is that the baseline assumption of society is that you're attracted to brunettes, the vast majority of love stories you see are about the protagonist being attracted to brunettes, and attraction to redheads is not seen as a neutral attribute. Attraction to redheads can get you beat up, or worse.
So it's important for the people who are attracted to redheads to feel safe, and supported, and able to express pride rather than shame.
But we're at a kind of a weird point right now. Things have improved enough that people who are even just a little attracted to redheads feel that they can say so (and feel that they're being dishonest if they "hide" it). However things have not improved enough that being attracted to redheads is nbd -- it's not yet neutral enough that the agonizing can be completely avoided. Declarations DO have an impact, so there's pressure to figure out what you're going to declare.
Hope we're on the path to true neutrality. Redheads (and lefties) really were seen as weird and shameful for a while there, we got past that somehow.
