I'll bet those of you who wouldn't mind felons getting guns back wouldn't want one living next door to you. Especially if they were a sex offender.
Begging the question and/or missing the point.
The felons I don't want to see get guns are the very ones who will get guns regardless of laws that say they shouldn't. This is exactly the same reason that gun control laws, in general, don't work: they only inhibit the law-abiding. If the felon is the sort who won't own guns because the law says he can't, then he's the sort that I fully trust with guns. You're assuming that having laws saying felons can't own guns will mean that felons don't have guns. Since the laws that say felons can't rape, murder, burgle, or thieve don't work, what makes you think the one that says they can't have guns will work?
And that's not even counting the number of felons who I'd trust with firearms while they were still on parole, even. The guy who got busted with just over an ounce of weed, and therefore got nailed with "intent to sell." The one who embezzled fifty grand from his employer to cover gambling debts. The CCW holder who forgot to leave his piece in the car when he went into a courthouse.
And
that's not even counting the number of felons who were wrongfully convicted.
Incidentally, your "especially a sex offender" comment doesn't carry much water for me, since I, personally, know a guy who's eight years into a twenty year sentence for having sex with his 17 year old girlfriend when he was 19. When they broke up, she got her revenge by accusing him of date rape. Her word against his, and now he'll never get to vote in a presidential election or legally own a firearm. Not to mention that he's in the sex offender registry, and he'll be tagged with that for the rest of his life.
So don't go betting on my opinions of felons and firearms, 'cause I'm pretty sure you'll lose.
