You may or may not have heard this story going around (go ahead and read it) about certain celebrities and pundits talking on the Second Amendment. Namely, "It's old fashioned" (Uh, the First Amendment doesn't say anything about the internet, TV, the radio, or telegraphs, but that hasn't stopped you), "It's not as important as the other amendments" (Yet these are the same people who can probably quote you Mao's "All power comes from the barrel of a gun"), "Well, maybe only hunting rifles" (because getting shot with a .270 hunting rifle won't hurt you nearly as much as a 5.56 evil black rifle, of course) and, my personal favorite, "We wouldn't be able to fight against F-22's and nukes anyway" (because that stopped the Afghanis in their tracks, didn't it?).
There are many ways to respond to such assertions, from the "First they came for the ______, and I didn't speak out because I wasn't a _______" argument, to the classic "μολὼν λαβέ!/cold dead hands" argument. Facts, figures, meeting their emotional appeals with emotional appeals of your own... in the end, though, I am starting to feel that the best response to any anti-gun argument is a nice firm um, "'Fruck' Off!"
We are winning. The anti-rights cultists have lost the narrative, despite what the media may print, and the only ones left on their side are the very ones you can't reason with.
