There is the Masons and private religious organizations like the KNOC and such. But really there aren't many left

The only true male privilege left is the knowledge, internal and external, that you have no inherent value, and therefore, any value you attain was a result of your own efforts. You will never need second-guess yourself, ask yourself "did I deserve this?", because no matter what it is, good or bad, you brought it about with your own will. No social networks or governmental offices or court powers designed specifically to making your life easier or your achievements given to you on a platter... At least in regards to your chromosomes.
