Don't have any problem with it. From what I can see, all it does is confirm to anybody who is desperate to know for whatever reason, that I shoot and therefore most likely own a gun, where I shoot, how often I shoot, and how good or crap I am at doing so.
Personally, I am happy to tell anybody who is interested (and some who are not) any and all of those things anyway.
And I would risk a fiver that those who are concerned about it still have a Facebook page? . . . . . . . . . . now that IS something to be MUCH more worried about.
