Yes, because what I was doing was objectively dangerous. Dueling used to be a commonly accepted practice, yes even killing - pity that ladder was pulled up! What about the children's chemistry sets that included uranium, mercury, and cyanide?
The uranium wasn’t really dangerous, unless you swallowed it. Common U-238 has a half-life of about 4.5 billion years, so it’s not actually very radioactive. The most dangerous thing about it is its toxicity as a heavy metal, but plenty of other elements of a chemistry set are at least as dangerous.
I think consensual duels should still be legal. Numerous states have laws about mutual combat where it is perfectly legal to beat the fuck out of each other.
