To the [insert mean-spirited, ethnically derogatory expletive directed at perceived sexual orientation here] who killed [insert name of beloved friend, family, and/or community member killed by armed assailant],
I shouldn't have to point out the obvious: guns don't kill people, idiots like you with guns kill people.
Thanks to you, [insert mean-spirited, ethnically derogatory expletive directed at perceived sexual orientation here], another child is dead (everyone, no matter how old they are, is someone's baby), and now the greiving community is now faced with increased scrutiny and imposition upon our lives by the very government that oversees and protects the social/political/economic system that is the very foundation of this so-called 'horizontal violence'.
Chances are this discussion is waaay beyond your realm of reasoning. Let me present this another way: killing your own people for petty reasons of 'wealth-building' or knee-jerk emotionalism amounts to doing the work of the ku klux klan for them (usually for free).
