Unfortunately, several individuals have turned the WE crowd into the US and ME crowd with their thinking.
I don't think it is at all surprising that people within the firearms-owning community (at least 100 million people in the U.S.) have different views, values, and beliefs about everything, including firearms. Gabby Giffords and Mark Kelly both tout themselves as gun owners and post videos and photos of themselves shooting, and they founded an organization ("Americans for Sensible Solutions") basically (ultimately) intent on legislating guns out of private hands. There has been a lot of attention in the past year to "minorities" (women, African-American, Hispanic, Asian, etc., LGBT, "liberal", etc.) in the gun-owning community and how to expand that "minority" membership. There are a lot of "differences" among gun owners, and some gun owners are quite outspoken on their beliefs about who should or should not have what kind of firearm under what conditions (e.g. "assault" rifles or pistols, disqualifying standards for ownership or CCW, CCW in general or restrictions on who, when, where, etc.).
That's all well and good. I favor a broad interpretation of First Amendment rights to expression. And when those people make public statements supporting laws that would curtail or end my right to "keep and bear arms" I believe it is my responsibility to counter whatever arguments or data they present to support their position. Not in order to "change the mind" of the person posting a "restrictive" view of Second Amendment rights, but so that other readers (possibly fence-sitting lurkers) can see a counter-argument and/or data that is perhaps more sound. Usually it's not too difficult to counter such arguments because the people making them tend not to be logically consistent and rarely have any substantial data (that will withstand critical scrutiny) to support their positions.
But in a group of 100 million people who have (perhaps only) one thing in common, gun ownership, there are going to be a lot of differing opinions, even about the one thing they have in common.
