But there's even something more basic, more fundamental.
A man who is apparently gay or bi is also at least partially in denial about a sexual preference.
It's a pattern of self-loathing that's all too common.
And understandable given a big portion of our society engages in demonizing members of the LGBT community.
From religious to political "leaders," the approval of this hatred is rampant in America, even in 2016.
Citing ISIS in the attack is just another way to "man up" in the denial.
Then throw in the ready availability of guns.
But without all that vile hatred preached across America, without all that subsequent denial, Omar Mateen never would have walked into The Pulse with guns.
It starts with hate.
And then hate grabs the guns.
