That’s such a weird point to make. Is it because to you, it seems like the line drawn is arbitrary? I cannot imagine any other reason. Certain words just mean certain things.
Markup languages are exactly as much “programming” as you marking a word and hitting “bold”. Which is to say, nothing at all. People are wrong all the time, and I have a very limited amount of fucks to give when it happens.
As for Scratch, it is a programming language. So, why would you think it’s a logical next step for me to say otherwise? Next, you’ll say something remarkably dumb in response. Resist the temptation, and do something more productive.
