Since the definition of "white" is inherently cultural, it varies from place to place and from time to time. Today, in US and Europe, pretty much everyone who cares about racial categorization would consider Irish "white". Historically, it was different, but that is only relevant when discussing history.

White is a pretty complex and non-obvious category.

Isn't it even more racist to replace them in a picture? Being told that your skin colour is too offensive to show sounds a lot worse to me than calling them "white" considering their skin is very white

Let me guess, you’re one of these people that think the Irish had it harder than African Americans in early US history.

Not true, that was made up by race baiting academics who were lying liars. It's absurd that anyone fell for it, frankly.

The lie originates with a Communist race hustler named Noel Ignatiev, also known for publishing Race Traitor magazine. A thoroughly unpleasant person.

is pale better?
