Language changes over time and words don't mean the same thing forever. The entire purpose of language is to communicate. So if you have a Mac and say you are a PC user, you are failing to use language well. Apple themselves helped facilitate that change. It can be less consistent with Linux on a PC, I agree. But language is an evolving meme (as per the original definition of meme, not the cat photos). And to not acknowledge that is like being a young earth creationist with language.
Do you also argue that anyone who is happy is part of the LGBT community?
This might be my favorite meme of the month. There is a problem though. How often do they actually talk to people to end up in this quandary?
I kid. All the love to my vegan arch users. Or arch using vegans. Whichever one you prefer.
