While this whole thing is a huge load of crap, the commanders unfortunately are forced into a CYA position.
The really unfortunate part of this is that the actual vulgarity of the true crimes are being diminished by the horrible solution presented by the leadership. It's just sad that no one has stepped up to say "No, we're not going down that road of banning everything. Sexual Assault and Harassment are wrong and will be dealt with accordingly. The consequences of doing such things will serve as the reminder to others not to follow down that path. Other things such as Pin-ups etc. are not wrong, and not even necessarily against the general culture of the U.S. or our heritage as a service. Lastly, should any male or female have any concerns with anything going on in their life, use the resources provided and you will see that this Air Force really does care to solve this issue".
This is hopefully a temporary phase, but at least in the meantime there are ways around this. An LT house with a bar can have whatever suggestive artwork, patches, etc. You can sing whatever songs you want there. Hell, you could wear whatever morale/friday patches you want there too. The house can be passed down through the generations of LTs. Or find a nice dive bar and become regulars. If you get close enough with the ownership, they might even let you put up some stuff on the walls. They won't mind a whole squadron worth of business on a regular basis.
As much as it sucks, if you move everything away from the squadron buildings, it can't be touched (for now). It does kinda kill the ability to just go chill at the SQ bar late on a Friday or whatever, and it will definitely be tougher on guys with families or who live on base, but it's basically the trend I noticed was used in UPT and still pretty much the way it is my crrent SQ.
