I don't believe that the collective right argument has been the sticking point from incorporating the 2nd though.
If the 2nd is collective, then only the states could file for incorporation - which they don’t care about, so they haven’t.
Only by declaring the 2nd individual can individuals then file to have it incorporated.
No “individual” ruling, no incorporation. SCOTUS ruling favorably on Parker would change that.
Could be. After all, the collective right argument is that the federal government cannot infringe on the state forming a militia.
Pretty hard to incorporate that -- a state shall not infringe itself to form a militia?
The collective right argument makes no sense against the states. Would they prohibit themselves from arming their own militia?
Many states have constitutional language similar or identical to the second amendment's language. They can't possibly be protecting their own right to arm their militia against their own infringement.
OTOH, if the second amendment is shown to protect an individual right, then those state constitutional provisions must also protect an individual right.
