It does neither our interests nor the RKBA to make extravagant arguments based on faulty information. It seriously damages our credibility.
Let's stick to the facts.
Which part about there being weapons in closets in those nations is non factual? Is the matter of the actual owner being the government of issue more relevant than their being kept/possessed by civilians(who remain subject to military recall)?
Not sure what exactly is extravagant either, but I'll clarify as
"Doesn't seem to be the cause problems for the Swiss or Israeli's, where "weapons of war" are commonly closeted in private residences".
