Yep, he just making money. I'm sure INGO want him to give up his paycheck because it is contrary to their stance.
I disagree. There are many that will choose to not fatten his paycheck by his or his business partners' 2A position. While I won't speak for everybody, I'm fine with him earning whatever he can legally solicit from anti-to-agnostic gun people. This is the great thing about how America is supposed to operate: he gets to set up a business as he sees fit, we get to comment and discuss his business with people we choose to assemble with, and let the chips fall where they may.
