I have been to their site a few times, and I have never found anything vehemently anti-gun there.
They seem to be primairly interested in keeping kids safe rather than advancing a political agenda. I might be wrong, but they advocate Eddie the Eagle type stuff.
I e-mailed them one time about promoting responsible gun mentorship, in other words, using a responsible adult to teach about safety, and allow youngsters to experience guns in a controlled environment. My point was that we should demystify guns.
I never heard back from them...
