Is "dyke" a black exclusive slur?

I would really like to figure it out. I have recently read some information on this word. And as far as I am aware "dyke" is a derivative and shortening of "bulldyke" which was a race (black/POC) specific slur. In the Wikipedia page "dyke" is spoken about as an evolution of said word; Into a slur that generally fits the lesbian and more broadly the sapphic community. I have read some other articles and I have only found mentions in past tension that "dyke" was a racial slur. In other LGBTQ+ Wikis I also have only found mentions of "dyke" applying to all races. Besides that I see a division in the community on this matter. It makes me confused. Are there any specific articles or any places in which I can read more specific information? Or any sources confirming any of the sides? What is your opinion as a sapphic?
