...then you inversely arguing that more guns does not make people unsafer.
Which is not true. More firearms makes for an inherently more dangerous society. Less firearms does indeed equal greater safety.
Even killing a person for their organs if it saves more people is a net gain in safety and health.
False analogy; not even close to the same thing.
This is not a Libertarian issue which loves to take major policy issues and apply niche cases to decide them.
Your right to steal property has been removed; it does not automatically threaten your right to vote.
Debate the main issue on the main points otherwise you are simply bikeshedding.
You said organ harvesting would be a net benefit to society; my argument is that it would not since we are killing a member of society purposefully.
confiscating an assault rifle would not instill the same fear as the Government killing your neighbor for his liver.
