The reality of the situation is that there is a minimum bar that the 501st accepts. Some people are OK with staying at a minimum bar, others do not. The 501st is home to both, which means the FISD is home to both. In other words, if you're an accuracy snob you better learn to tolerate your basic brothers as they're equal members too. And if you're just at the minimum bar, you better get used to people always wanting to be more accurate.
However I do notice that people who just want to get a basic suit and move on don't spend much time on detachment boards once their suit is put together (this or any other detachment, so FISD is not unique). So while we're here to help, please forgive the membership if they always nudge folks to be more like themselves.
