Two equally ridiculous concepts, that liberals can deny with a straight face one exists, while bloviating about the pervasiveness of the other.

Green was a thing before Ireland was. So THEY are the ones culturally appropriating a public domain color. Decent countries use a color combination, so seeing them together can represent the country. You can't just claim "green" to be exclusively your symbol. As the Cincinnati baseball club when the DAR asked them to change their name lest they been seen as pro-communist, "We were Reds before they were."
