Vexillology

Yeah I tend to agree. He says being able to recognise it doesn't matter and that it being simple enough for a child to draw is irrelevant. I can see his point with the latter, and I think he makes a good point about how people have made allowances for flags like the US flag but not others. But I also think the ones with seals or coats of arms really go too far, to the point that they often genuinely cannot be clearly distinguished if looked at on a flagpole from a distance, among a number of other flags, when the wind isn't blowing. Because that's the situation that a good flag design should be clear.
