Just a hunch I have, nothing more at this time...
But it seems that those of us who tend to embrace a progressive worldview can embrace a view of unity in the LGBT community -- that there is good to be gained by including all who are the many combinations and permutations of the flavours of sexual orientation and gender identity--
--while those who tend to embrace a conservative worldview will endorse a keep-to-our-own-kind, I-got-mine-jack, and we-have-nothing-in-common-with-you ideology.
This is not a binary, but a spectrum, but with sizable clusters near the poles and in-betweeners thinly distributed through the midpoints.
And the groupings I've mentioned will also share other correlations with either progressives (for single-payer health, for gun control, for social programs and protections for minorities,) or the conservatives (for freedom of gun ownership, strong defense, against social programs, for the 'opportunity to fail', etc).
Again, this is true for the groups -- individuals have more wiggle room.
Anyway, my 44 cents (two 1913 cents, adjusted for inflation...)
