I'm inclined to agree with neoncowboy on this one. It seems as though we're grasping at straws trying to find actors/celebrities who may actually share some of of views on guns. However, the reality is that few of these people ever espouse their views on RKBA, or whatever level of passion they may have for guns, routinely, regularly or even publicly in any sort of high-profile manner that would make a difference.
I respect guys such as Gerald McRaney ("Simon & Simon," "Major Dad,", etc.; a long-time, outspoken gun advocate), Tom Selleck, Charlton Heston. These guys always made public appearances in gun-oriented settings and were tremendous advocates for RKBA when they appeared on talk shows, etc.
Others, such as some of the young actors and actresses occasionally mentioned in the "pro-gun celebrity" threads (which crop up every other month, it seems), may have brief flirtations with firearms and share their excitement about an early range experience or working with guns in films ... but then you never hear from them again.
I respect only the actors/celebrities who are outspoken on issues that they know may not be politically correct. Few enough of them make use of their celebrity to help our cause. Hence, I'm not gonna jump on the bandwagon and get all excited 'cause some new hot young actress professes her love of shooting after filming the latest zombie-killing action flick ...
Frankly, we in this country seem to care all too much about what our celebrities think. As I've noted before, most of us have far more real-life experience than any of these actors/celebrities, most of us are better-educated, and almost all of us know far more about the things that matter in this life than any twenty-five year old, college-dropout, multi-millionaire actor ...
