On many guns, switching the safety to the "fire" position exposes a red dot, red meaning "hot" or "fire".

Yeah my CZ pistol is like that and it’s fucking terrifying because in my mind red means stop or locked. I actually feel more secure with my Glock because it doesn’t have a safety so it’s unambiguous. If I point my Glock and squeeze, I know it’s going to fire.

The red of a stop light makes a lot more sense in relation to the red of a fire mode on a gun when you think of red being "caution, unsafe" instead of just "stop". Just like the red of a STOP sign is to caution you into paying attention of the danger of the cross traffic, not necessarily just stopping.

Red lights on top of towers isn't trying to tell planes and helicopters to stop, its telling planes to exercise caution around the tower.

Or like at a railway crossing. The flashing lights indicate danger, and the barriers drop. According to GP, the lights should flash when the barrier is not dropped, because now it's unsafe, FFS.

Reprogram your brain for "Red means danger, green means safe" and you'll do a lot better.

Red at a traffic light means there's a danger so you stop. Green means it's safe to proceed.

Red on a gun safety switch means danger because it's live.

The red wire is live and dangerous. The green wire is earth and safe. (at least true in Europe).

Ah, my CZ is a DA/SA with a decocker. I'd recommend it! No manual safety, but you can hold the hammer forward while holstering.
