Guns and fertilizer are very different products. Guns were specifically developed with the purpose of killing. Their main use besides recreation is killing people.
Don’t understand the downvotes to my comment. The person I am responding to said “Should we stop making guns because someone might kill another person”. That is in fact one of the main reasons of guns, specifically because they are used to kill other people. I didn’t downvote that comment, I did not pass any moral judgement on guns. Instead of silently downvoting, it would be better to explain why you disagree with my comment. I believe I am operating in good faith here.
