I'm sorry you feel offended, but you did write an article online with a deliberately provocative title. If you do that, you need to be able to deal with criticism. And not considering concurrency when mutating globals in C/C++ is not acceptable (never mind good) practice. You can say "threads are out of scope" till your blue in the face, but if you write an article with the thesis "globals are good, actually", you have to be able to deal with people saying "they're dangerous because of thread safety". That is a legitimate criticism of your thesis. In addition, my other criticisms of your code (overflow and properly scoping statics) have nothing to do with concurrency.

Has anyone told you to never use atomics? Have you not heard lockless programming is hard? (I saw this recently https://wiki.libsdl.org/SDL2/CategoryAtomic,) Have you written multi-threaded programs? I written two large ones. The fact you're suggesting non-experts use atomic is insanity. As well as criticizing 'overflow' in an article showing minimum easy to understand code to be read by people using completely different languages
