Nobody will care about it after Erdoğan is gone. We've been called that for a long time and it never really bothered anybody. We call India "Hindistan" (land of turkeys) ourselves and nobody seems to see the irony there.
You have the cause and effect reversed. Hindustan doesn't mean land of turkeys, it is that the bird is named after the country (Hindustan is a semi official name for India, ultimately both names come from the Indus river) in some languages. In my understanding it is because the bird is actually from the new world, so the existing cultures made up / didn't know where the bird was supposed to be from, and called it "bird from India" in some cases.
I didn't mean it that way but if you look at the name and all the other -stans that's how it translates. It's quite fascinating how various countries name the bird. Another similar example in Turkish is the one for Egypt. I believe it's Misr in Arabic. In Turkish it's Mısır, which is the word for 'corn'. I am not aware of them complaining about Turks calling their country corn. :)
