I dunno.

They didn't ask me if they should.

(and the only- and I mean only- reason I'd be inclined to say they did kill Kirk was because they just let everyone know they most certainly did not kill him.)

There's a funny babylon 5 clip here. the backstory is that her boss, Captain Sheridan, asked her to slip in that nothing happened in sector 83x9x12. She balked saying that her thing not being propaganda. She gives in, because in point of fact nothing happened, at all. He also did other things like having a fleet of ships move around and shoot random rocks in quiet spaces... all because he was trying to get a cantankerous group of allied worlds (ironically named, "league of non-allied worlds"...) to sign a thing bringing them into a more formal alliance. These worlds saw the whites stars shooting at the rocks, saw the announcement, and were like "White stars don't shoot at nothing! there must be an enemy we can't see!" (and then handed him everything he wanted.)

"White" is an ever-moving target, dancing on the whims of whether the suit-and-tie-wearing white guy thinks he can get you to build him a railroad.

So, the answer is yes and no.

According to Charlie Kirk? Nope.

For white supremacists it’s not really about skin color (well, some might actually be that stupid,) but rather about culture, and their culture being “special”

Keep in mind, 19th century people saw them as a distinct race, and Kirk’s views (as well as, for example hitler’s) stem from that.

To be clear, Kirk and his ilk are assholes with a very backwards view of the world.
