So why not go from there and extend this same principle to just about anything? Is a general practitioner a failure just because he or she is not a surgeon? Hardly. There are strengths to every field. Assessing the quality of the strengths and weaknesses is vital in this day and age. Given the fact that physicians (including us chiropractors) are getting really friggin sick and tired of dealing with insurance hassles, HMO red tape, malpractice requirements, state and national board policies and guidelines, less time for patient interaction yet more time devoted to paper chases, slow but steady decline in income, very little family time, rising costs of education, the problems associated with internships and residency, research requirements with certain positions, continuing education requirements, frugal lawsuits, and the higher rates of stress, divorce, death, suicide, etc. All of these factors stacked up on top of each other actually accumulate. So when you start looking at all these downsides, then other related professions start making more sense. Not that nurses have it easy...the REALITY is that if it were up to doctors to care for patients on a minute to minute basis there would be BIG problems. Here's the truth: a doctor can do many things for the greater good of the patient...but a nurse makes sure it all gets done and runs smoothly. If you think a nurse is opting for the easy way out I urge you to ask a good doctor how valuable they are.
Nurses are in need just about everywhere. There is excellent job security and competitive pay. The more in demand a nurse is, the more money can be made in some cases. I personally know a nurse who works her butt off but makes probably close to 100 K. She is not exactly the exception either.
Being a nurse has nothing to do with gender, whether a person is a homosexual or not, has a low self esteem or didn't make it to med school. It has to do with choice of occupation. Given that plenty of doctors are wishing they had done something else, yet not nearly as many nurses are, it kind of makes you wonder who chose more wisely when all things are considered. If you want patient interaction and the genuine opportunity to care for people on a daily basis without as many headaches, then nursing is the answer.
If you know for a fact that male nurses fall into the categories you have mentioned then you should consider writing a abstract and submitting it to a statistical research colloquium for review. You'd get laughed out of the place I can promise you.
If you have factual evidence then show it. Otherwise it's an opinion.
