My senator, Roger Wicker, has introduced the Military Religious Freedom Act of 2012. A couple of things here:
1.) It's very interesting that it bears the exact same name as the Military Religious Freedom Foundation. I'm sure that's just an accident. Surely, the use of such Orwellian language could not be intentional.
2.) From TheHill.com blog: 'Under current Pentagon rules, military chaplains may decline any involvement in gay marriage ceremonies.' It's obvious that this bill is just more pandering to the theocratic right.
3.) The chaplains already have plenty of 'religious freedom'. They have so much of it, in fact, that they feel the need to force it upon vulnerable young cadets.

A real 'military religious freedom' act would impose penalties upon chaplains (and officers) who used their positions to coerce and pressure the 'unsaved' into their evangelical programs. Maybe Senator Wicker will work to defend the rights of soldiers who don't want christian fundamentalism shoved down their throats?

That, as Sheldon Cooper says, was sarcasm.
The text of the legislation follows.
