Before you get your panties in a twist, consider the same sociologically speaking analysis of pet ownership, dogs vs cats.

Cat ownership is abnormal.
REFERENCE: WASHINGTON, D.C. -- Gallup finds 7.1% of U.S. adults identifying as lesbian, gay, bisexual, transgender, or something other than straight or heterosexual. The percentage has steadily increased since Gallup first measured LGBT identification in 2012.
NOTE: There are approximately 70M (60%) dog owners and 45M (40%) cat owners in the U.S.

All of this, plus throwing out results that don't agree with their preconceived result as "outliers", using bots and false reporting to pump up the results towards their desired outcome, and if all else fails, just straight up lying by making crap up while claiming that it was an "anonymous study/poll".
I have little doubt, I was only speaking to things I had witnessed/noticed for the brief period I worked as a phone monkey for one of those polling places. Though, at that time, bots weren't really an option.
