This is really tricky for me and has me considering all sorts of philosophical questions. None of what I say is directed at you individually, but at the hypocrisy I see in the conversation around gangster culture.
On the one hand, I agree that venerating gangsters is a folly, and bad for our national health, culture, and development of youth. On the other, I perceive a pretty big double standard in America on which gangsters are considered ok to be venerated.
On the whole, America makes it clear that we like gangsters - the old west and prohibition are glorified. Films like the Godfather trilogy, all the spaghetti westerns, or even boys in the hood show that we at the very least are sympathetic to gangsters. Tony Soprano, Walter White, maybe even Omar from the Wire....all characters that we've deified. We celebrate Jessie James still - a bank robber!
In regard to Walley, I really just think that there is a certain segment of the watching audience that is going to be offended because the type of gangster he is emulating. Because from where I sit, I feel like I live in a country that LOVES gangsters and fetishizes guns. Both are weird to me.
