These folks apparently feel that something more forceful might be in order if KKKLetus and friends decide
to go on a bashing spree and they become a target.
That is their right, and I wholeheartedly support their informed choice to exercise it.
Of course, LGBTQ people aren't the first persecuted minority with members that made that decision:

This Nonviolent Stuff′ll Get You Killed: How Guns Made the Civil Rights Movement Possible
Description
Visiting Martin Luther King Jr. during the Montgomery, Alabama, bus boycott, journalist William Worthy almost sat on a loaded pistol. "Just for self-defense," King assured him. It was not the only weapon King kept for such a purpose; one of his advisors remembered the reverends Montgomery, Alabama, home as "an arsenal." Like King, many ostensibly "nonviolent" civil rights activists embraced their constitutional right to self-protectionyet this crucial dimension of the Afro-American freedom struggle has been long ignored by history. In This Nonviolent Stuffll Get You Killed, Charles E. Cobb Jr. recovers this history, describing the vital role that armed self-defense has played in the survival and liberation of black communities. Drawing on his experiences in the civil rights movement and giving voice to its participants, Cobb lays bare the paradoxical relationship between the nonviolent civil rights struggle and the long history and importance of African Americans taking up arms to defend themselves against white supremacist violence.
