Growing up in the '50s I was blissfully unaware of the pervasive cultural propaganda dished out by TV, most evidenced in the "family" shows like Beaver. I became conscious of this ongoing onslaught of far more than consumerism rah-rah content when I grew up, but this episode shows it more obviously than usual.
Ostensibly playing on the childish aversion of young boys to young girls and "mushy stuff", here made explicit when the Beaver flees as the only guy at a birthday party filled with young girls when one suggests they play Post Office, the payoff is right out of the NRA's handbook.
Cleaver finds himself in a room filled with mounted animal trophy heads on the wall and a case full of firearms. The birthday girl's dad beckons to him from an easy chair and they chat, leading to him showing him his gun collection, including a rifle used to kill buffalo ("and Indians too") as well as the typical obeisance to the romantic outlaw Billy the Kid. Upshot of this romantic view of America's obsession with guns is a happy ending that implicitly celebrates boys being brought up to respect manly things, and postpone sexuality and obsession with the Fairer Sex till later.
Of course TV shows and the money-grubbing sponsors of same are not to blame for all our society's ills, but this paean to the Gun Culture is more than annoying, as the purveyors of deadly weapons are (and were) not allowed to freely advertise on television so this form of unsubtle advertising for their trade had to suffice. And ramming home all sorts of stereotypes, particularly the portrait of young women presented in this episode (notwithstanding the usual quality performance by Billingsley as loving mother) plus the conventional wisdom about the extermination of Native Americans -good for a quick laugh - is disgusting.
