I had plenty of experiences with similarly useless debates as a teenager on the internet twenty years ago. Think of providing code examples with indentation that the reader didn't like. At least being more inclusive is a more worthwhile goal than finding the perfect indentation, but yeah, neither answers the question at hand

Could it be that you now recognise the uselessness of such a response whereas, when you were younger, you didn't know any better and took it as-is? Because I think that's almost certainly the case for me, rather than that it is an exclusive feature of modern times that some people berate others on minor-to-irrelevant points
