You have a right to bare arms. For long sleeves you’d need a permit.

Probably the closest RL example you'll get, but we had kind of a stir at the hospital I work at, maybe... idk, 5 years ago now? Anyway, patient had a prosthetic leg, and kept a handgun hidden inside it. One of the nurses or techs was giving the dude a spongebath or something and spotted the gun; called security, and the dude ended up getting escorted out by police.

No idea if he was actually charged with anything, or if he just got 'fired' as a patient and banned from the hospital.

Gotta be part bear too

No, flamethrowers are regulated as landscaping equipment not as arms. We don't have the right to arm hoes

I would say no you aren't protected because the US Constitution may as well be toilet paper now.

You have a right to bear whatever arm you got

Jokes aside yes... Because flamethrowers are not actually restricted by federal law or by state law except in Maryland.
