"Are you a sportsman? Do you like to shoot pistols at targets? Well, get on the subway* and go to Maryland. There is no problem, I don't think, for anyone who really wants to have a gun."
Let's forget for the moment that the 2nd Amendment has nothing to do with "sports".
Imagine if Martin Luther King Jr. had Breyer's attitude? Would he have avoided all those whoopings by the police and moved to Canada?
Imagine if America had Breyer's attitude during WWII? Would we have told the Jews to just pack their stuff and leave.
What would Breyer tell victims of gay bashing? "Don't like getting your face kicked in? Then hop on the bus and go to San Francisco."
Would Breyer tell Muslims, "Want to practice your religion? Then go to Mecca."?
It should be painfully obvious that Breyer's way is the way of the coward. His message to the American people is to run away from any fight for your rights. It's a good thing we don't depend on him for any important, life-changing decisions... Oh wait.
* ADDENDUM: Can you even legally take a gun on the subway in DC? It's worth finding out.
