Anti-gun activist David Hogg is far from reluctant to share his thoughts.

Earlier this year, Hogg posted a tweet that read: “This is a tweet for for [sic] the founders of the gun violence prevention movement started centuries ago by almost entirely black, brown and indigenous lgbtq women and non binary people that never got on the news or in most history books. We may not know all your names but thank you.”

Erin Palette, the national coordinator for the Pink Pistols, the largest “pro-queer gun group” in the United States, described Hogg’s tweet as “completely careless in its inaccuracy, and therefore callous to the injustice done to those people whom he is claiming to champion.” Referring to the “centuries” of gun control that Hogg alleges existed, Palette writes, “I have no idea how he arrived at this number, and I doubt anyone else does, either. If there is a history book that tells the story of how non-white queer women and transwomen started a gun control movement in 1820, then I would very much like to read it.”
