I agree, but so far the Supreme Court has only found that the constitution gives you a right to own some kind of gun - not specifically anything they are trying to ban right now. Everything else is just our opinion.
Not to mention, we all oppose somebody's constitutional rights on some issue, whether it's the Westboro Baptists Church, the KKK, the Brady Campaign, Occupy ______, or the democrat party.
The person who has nothing for which he is willing to fight, nothing … more important than his own personal safety, is a miserable creature [with] no chance of being free unless made and kept so by the exertions of better men …. John Stuart Mill
