I'm a student nurse lurker who felt compelled to post about this. I appreciate your sentiment, but your refusal to acknowledge that this was, in fact, an attack on the gay community and that the gunman did, in fact, target these people in this place because he knew most of his victims would be gay makes you part of the problem.
It's tacit homophobia like this - the refusal to acknowledge LGBT people and their spaces as their own - that snowballs and grows to create a culture where we're seen as "less than," or where our unique and continued struggles are ignored because "we're all humans." It's no different than saying "I don't see race - we're all American citizens" when the unfortunate fact of the matter is that white and black Americans have incredibly unequal experiences today.
I appreicate your viewing this as a "human tragedy"...but maybe take a step outside your perspective and be willing to view this as an attack on a community that's not yours, and that you don't understand (I'm willing to bet on this considering you claim you "would go out to party with my homosexual friends back in the day" - there's nothing we love more than being objectified).
Try to understand what it feels like to have one of the very few safe spaces you have - maybe the only space in your entire community where you feel completely free to "be you" - be completely violated.
Empathize with us. Grieve with us. Acknowledge us.
