Here's another way to look at it, for any SOF hopefuls. Situational awareness has already been touched on i.e. knowing what is going on around you/knowing your current environment. As SOF, and really as a soldier of any type, this is something you need to have all the time not just when you're deployed. You always have to have SA on your surroundings.
When I leave our team room my appearance looks like a recruiting poster, it's not because I'm a motard but because my SA of my surroundings tells me that the wings and bubble on my chest draws attention both good and bad. I know that it would give some senior SNCO or Officer the biggest hard on to life me out for a shitty uniform haircut or shave. I do the same thing in the rear I do in the field, I avoid compromise. Don't think the exact same thing can't happen over here maybe not something that small, but if you get flagged as that guy who wants to push the limits of the standard in a bad way you will go away. It's as simple as that.
Final thought, if you can't work with and manuver around someone in your chain of command how do expect to do it with a stubborn leader of a different culture, which is one of the core task of the unit you want to join? Judging from the reasoning in your post you either need re-evaluate your thought process, some more time to mature before you try to come over here, or you need to seek life else where.
