Umm...I'm not sure you're familiar with the actual reasoning on the table here, or else you're ignoring it. The framers certainly didn't expressly condone (or "have in mind") interracial marriage, either, but I hope we can all agree that laws forbidding such marriages were unconstitutional.

Perhaps you'd like to have those marriages annulled, too? At least until all interracial couples join the NRA?
