It is a choice, but it is still a choice to embrace an outward-show of clothing, living, etc, mega legalism. It is mega legalism. And no, I personally wouldn’t want anyone to make this choice even though it is theirs to make...
Legalism implies to me that they are saying you have to live this way in order to attain salvation. As far as I know, that isn’t their stance. They say, you have to live this way to be a part of our community. So, to me, it’s nothing more nefarious than a set of homeowner’s association rules.
