I don’t know about upset.
You refer to it as gnu/Linux, I won’t be upset. I’ll just slightly roll my eyes at your choosing to utter such an inconvenient word to make a point that doesn’t really need to be made. But ultimately it’s your breath that is being wasted not mine, so I don’t really care.
You start arguing about it, then it gets annoying because give it a rest. I am perfectly aware that gnu is a core part of the whole thing, I just don’t think it matters that I verbally pay tribute to it every single time I mention Linux. One word is enough to let you know wtf I’m talking about 99.999999% of the time, so I’m not adding another one that’s already implied basically always. Still not upset though.
All sounds are short clicks that just repeat rapidly, if you think about it.
