What would be "bad faith" would be to portray a wide swath of firearms law which you so gleefully describe as "enshrined" prior to 2008 (and especially prior to ~1930) as anything more than a racist and systemic effort to disproportionately strip minorities (especially blacks) of their second amendment rights. As a pragmatic reality the white INDIVIDUAL could buy and bear even machine guns up until the 1920s with basically no scrutiny, despite your "enshrined" reality that might suggest otherwise.

Of course, perhaps on this occasion the "bad faith" claim is merely a face-saving attempt or a mental shut-down after various mental gymnastics come against the hard reality of the fact patterns present.
