This old soldier's opinion: That is disgusting! The Marines are "The Few, The Proud" and rightfully so. Back when I was an instructor at an Army school, my Marine students were head and shoulders above the other students I had. Wasn't that they were smarter, they just worked harder and paid attention.
They don't need to be "inclusive". They need to remain just what they are; a highly trained, elite force available for both amphibious and air assault.
