That's a different issue, on the level of the individual themselves. A problem however is the taking away of options for those who want to do otherwise (by forcing people into a narrow box of a form of 'acceptable masculinity') instead of using it as a 'free to wallow' card- sides, folks who want to do the latter will do it regardless, just perhaps in quieter and more insidious ways.
Something a bit funny and interesting, though. I've always hated these kinds of 'gender roles' even before I knew of the term, ever since I was a child. I hated being told what to do or how to do it and being told off for, for example, liking things that were 'feminine', or displaying fear. My counter for that is always this, and it turns the argument back on the person and really only makes sense- and I wonder HOW on earth people don't realize this? That if you really want me to be masculine, traits of being so include being independent and having a say in how you conduct your business without cowing into pressure. That is exactly what I am doing. Now leave me and my baking project alone before I brutalize you with a moldy baguette.
