That's a thoughtful gift.
It shows that she appreciates and respects what you think is important. Anyone can buy a few DVD's or a PS2 or a bigscreen... but they don't really mean much (as cool as they are).
No need to propose to her over something like this (if that's even what she got you)... lol there really ARE more imporant issues in marriage than gun control, no matter what this board thinks.
But, it's a big plus. Definitely worth holding on to her for a while.
Good luck. I like NRA memberships... they help all of us.
