Nope. Can't claim to be a 2-A supporter and qualify the statement with exceptions.
So who are you .. the self-appointed arbiter of who gets to call themselves a 2A supporter? There are no rights that are absolute - not now, and not at any time in American history. Government has been encroaching on all individual liberties from the get-go; just the names and 'issue' changes over time.
CC reciprocity and HPA are dead in the water for the moment. And they will never be revived if the 2A community defends bumpfire stocks.
