Meaning the specifically gay/lesbian are fewer than 3.8%.
Gallup reported here May 21, 2015:
PRINCETON, N.J. -- The American public estimates on average that 23% of Americans are gay or lesbian, little changed from Americans' 25% estimate in 2011, and only slightly higher than separate 2002 estimates of the gay and lesbian population. These estimates are many times higher than the 3.8% of the adult population who identified themselves as lesbian, gay, bisexual or transgender in Gallup Daily tracking in the first four months of this year.
---------------------------------------------
While the least educated among us are off on the estimate by a factor of over seven, the smartest, with post-graduate degrees, are still off by a factor of nearly four, according to Gallup.
And you thought belief was purely a phenomenon of religion.
