a boolean named is_person_standing seems fine when person states other than standing don’t matter to the program, except for the fact they are not standing.
which leads to: name the boolean based on the thing relevant to what you’re building (this applies to other variable types, as well).
I’d just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!
I mean, you could similarly reason that bisexuals aren’t welcome (both gays and lesbians are solely attracted to the same sex, after all), or that asexuals aren’t welcome (you can be asexual and heteroromantic, after all), and so on. I think, ultimately, that unity between us is important, and allowing the umbrella to protect all members of gender, romantic, and sexual minorities strengthens the overall cause rather than weakening it.
