Are you really saying that gun rights and civil rights are on an equal footing? That someone being required to show identification before purchasing a firearm is of the same scale as blacks being lynched for trying to vote? That's a stretch.
As far as amendments of the constitution? Yes they are on equal footing there. I don't have a problem with someone being required to show id to buy a gun much like I don't have a problem with people having to show an id to vote. I actually find it as more of a financial hardship to buy a gun in many places since they require permits or classes to be able to purchase handguns or even rifles in some areas which can end up costing hundreds of dollars in classes and training, at least once. Versus paying $20 to get a drivers license, or less for an id card used for a lot of things, much like a valid state id is required to purchase a gun or ammunition in possibly every state. I know I had to show my photo id, drivers license, at Walmart to buy ammo before, though last time I went to vote, 2012, they asked for my name and to present my id but they didn't look at it for more than a second and it never left my hand.
Edit: And before anyone asks why I didn't vote last year I'm in unincorporated county area and the county didn't have anything to vote on in 2013 that I cared about. On top of that I don't have a party affiliation so I can't vote in primaries for Dem or Rep here.
