Equally as important to arming yourself is joining LGBTQ+ friendly/organized community aid groups near you. Being armed might save you if, humanity forbid, you ever find yourself in a situation where you need to defend yourself, but being part of an armed and organized community aid group WILL make fascists think twice, and it WILL make the world a better and safer place for the LGBTQ+ community.
The Socialist Rifle Association, John Brown Gun Club/Redneck Revolt, Pink Pistols, Huey P. Newton Gun Club, Armed Equality, Operation Blazing Sword, and Latino Rifle Association are all LGBTQ+ friendly organizations that can provide valuable resources to members of the LGBTQ+ community who are newly armed, looking to arm themselves, or looking to get involved in community aid even without carrying a firearm.
If you don't wish to carry a firearm, at least carry a non-lethal means of self-defense. OC/pepper spray, cable whips, and, where legal, tasers and drive-capable stun guns are great, and you should carry one even if you also carry a firearm. Make sure to look into local laws when choosing a means of self-defense as some things may not be legal in certain areas or may require specific licensing. Avoid relying on knives, kubatons, spikes, etc., as a form of self-defense. These are not effective tools without considerable training in specialized martial arts and are likely to only escalate a confrontation. Try to attend a basic trauma care (FAST or Stop-The-Bleed) class and keep a tourniquet and chest seal handy, if not a full trauma care kit. If you frequent places like bars or clubs, ask the owners if they have an active shooter response plan ready and if staff have access to a first aid/trauma care kit.
I hate that this is the rules we've got to play by, but the game is getting played regardless of whether or not we like it. The good news is, the fascists aren't nearly as tough as they like to act in a group when they're the only ones with guns. All it takes is a few armed people in black clothes and pride flags and they scuttle away like the cockroaches they are. Stay strong, and be who you are.
