1. Yes, completely. You're denying a legal right to one group of citizens, when others possess that right. That's discrimination, and the Constitution doesn't support that. You can't not hire someone because of ****** orientation, but denying them other rights is ok? FAIL.
2. Women have the right to choose; their bodies, not mine. Do I support partial birth abortions or late term abortions? no, but I haven't heard anything yet about that being on the table for reversal.
3. The prison at Gitmo has only hardened the resolve of all these "terrorists" around the world. I assume that's the pampering you refer to. If the government had put those guys on trial right away, you think a jury full of Americans would let them walk? And no matter how tight or controlling the security, you will never prevent a single guy or a small group from killing people. It is impossible.
4. No, but there's a lot of guns that shouldn't be purchased. And the 2nd Amendment doesn't make it legal to carry assault rifles.
