All those people who feel Carl should close his shop are his customer base and their purchases provide his livelihood. He does need to consider their opinions if he wants to attract/retain their business.
I have known Carl for many years and probably have a greater connection to him than most reading this so I am not anti-Carl nor do I feel I am bashing 4S when I say they should close tomorrow and Carl himself should attend the Statehouse rally (disclaimer: I do not know if Carl is or isn't attending).
The firearms community has enabled Carl to have a lucrative business. He is one of the biggest FFLs in this state. It would be a fine show of solidarity for our community if Carl were to step up in this way.
Not only should Carl close and attend the rally but Carl's position as one of the Premier FFLs in the state allows him the unique ability to promote the Rally through his e-mail blasts, tweets, website hits and yes, a sign on his door tomorrow stating, "Closed for Freedom".
