He likes firearms but that doesn't mean he likes them in the hands of civilians. I haven't heard anything to really give a hint if he leans one way or the other. That said, MailCall! is the greatest show of all time.
From what I have seen from him,outside of Full Metal Jacket,in his tv series "Mail Call"(I think that it was the name,of his show.) he seemed very interested in firearms,he was an ex-marine(a good sign.),he seemed as much a hardass as his screen character Gunnery Sergent Hartman,was and he is a guy,that isn't pc at all,but one who would actually speak his mind.
He is also,quite funny,in a serious way.
He would certainly tell Micheal Moore,Hiliary Clinton,Diane Fernstein,etc,etc,where to shove it.He would probably tell them:"What are your major malfunctions,you liberal numnuts!" and "Shut your mouths,scumbags."Or Micheal Moore,been given the Private Pyle treatment,on one of Moores anti-gun documentaries,by him,dressed as Hartman.
Oh and how do you know,what he might thinks about civillians rights to guns.If he became the NRA president,then I think he wouldn't be much of a politition or a diplomat,to the anti-gun groups or to the top-brass,in the Governers office-but he would speak his mind and respect your rights,instead of selling his soul,to the antis.Some one who is more refined like Tom Selleck,would probably win over the sheep,but there is something about Ermy,that makes you think,that he is right for the job.
We could do with him in the UK,too,as president of the BASC.
Really,he would annoy the GCN and that would be funny.
Micheal Moore,once pro-gun,now seemingly an anti.
