It is STILL irrelevant to the issue at hand. If all you want to do is argue basic constitutional law & theory and how to maintain 'democracy' etc....that is one thing. It is quite another to debate the details of possible variations in one amendment with hypothetical musings about possible abuses of another. In theory, ALL aspects of those amendments are subject to change, given enough need and the will of enough people and states.
I will debate attempts to alter 'freedom of speech' rules separately.
The 21st amendment repealed the 18th...you would not have wanted the discussion of your right to own guns be linked to the prohibition OR allowing of liquor, would you?

The very fact that such entities as The Washington Post and many well-known pundits agree with me indicate that it IS a serious issue and not a silly whim of a few wimps who are afraid of guns.

But, that relates to one of my points....even IF freedom to own guns makes YOU more comfortable about personal security, it won't help the millions who are NOT capable, psychologically, emotionally or physically to own & operate firearms. If proper restriction on BOTH ownership and types of weapons and ammunition were in place and enforced, we wimps would not fear the idiots so much.
