If that's one way of interpretation, that you think there ought to be significant mentioning of 4 divisions of ethnic groups, then in the Formosa Cross I proposed, you already have four equal quadrant, occupying equal area, without hinting at which one is which.
This might be foresight but individuals may choose different interpretations for the Formosan Cross. Maybe someone will think that christianity although being a minority is represented and respected? I'm pretty sure a lot of DPP supporters do not NOT vote for DPP because it there is a cross in the dpp flag.
From what I recall the design of the cross means cross-road, meaning that the dpp didn't know which way Taiwan should go, and they advocated there should be a referendum.
My design carries no such meaning.
