I'm not sure the people you characterize as Fudds exist to any significant degree. I don't have a military-style sporter and don't even long for one. But I care greatly when attempts are made to ban them because I am a fan of sound and well researched public policy; selective gun bans are based on slapdash, impressionistic opinions that are formed in a research vacuum. Everybody who wants a mililtary-style sporter should be able to own one, and if anyone can pass the review and afford the tax stamp, he should be able to buy a selective-fire rifle as well.
I will take a factory-scoped Mannlicher Schoenauer carbine over an AR-15 any day of the week. But I don't care if you like the other style. Feel free to buy any of them that a manufacturer may have made in hopes of selling them to me. I support the rights of others to acquire the specific firearms they want, subject only to the common-sense limitations of mental illness, criminal record, or restraining orders issued in response to a demonstrated capacity for violence.
