It's simply true, and for anyone that has studied the issue, the entire concept of "women inequality" has more to do with politics than reality. Your responses tell me you've been drinking the kool-aid as well.
The bottom line, if any coworker calling a male nurse a "murse" should be handled the same way a man would be calling a women anything else than the politically correct norm nowadays. Anything else is a double standard.
Also on the fat, old, ugly, bitter nurse, we don't seem to have a shortage of them. Congrats on the achievement! The industry would do well to have more male influence IMO, and there is a clear reason a male gets paid more as a nurse in many settings, albeit how small that difference may be. It's supply, demand, as well as the other traits a man brings to the table such as less call offs, more reliable, more physical, less backstabbing drama among coworkers, etc..
If women want to be "equal" in other settings such as business, they can also take on the "equality" of the required hours worked, productivity standards etc.
Just the facts.
