Proposal

Look all I am saying is that the term "Iranian" is a very loose term and people can get easily confused when they see this. Iranic would be a better term to use. Nontheless, there is no doubt that the Kurdish language is a bit similar to other languages such as Persian but there is also a difference as well. I am speaking as a Kurd myself. There is evidence that the Kurds have the highest chance out of all the other ethnic groups of being descendants of the Medes, all one has to do is look at lingustics. Although, it is also important to know that the Kurds have been in the middle east for a very very long time, and there have been many other empires/people as well. There have also been, for example, claims that Kurds are also descendants of the Gutians. It all boils down to what you believe, but to say that the Kurds are an Iranian people, is sort of going overboard. 

Kurds have been mentioned for a very longtime by many different people, including the Sumerians!

Nonetheless, I think there should be a change. I sort of agree with the Proposal above but I believe it can be better. Heres what I think should be written

Kurds are an ethnic group in the Middle East that inhabit adjacent parts of Turkey, Iran, Iraq, and Syira known as Kurdistan. The Kurds speak a language known as Kurdish, which form a subgroup of the NorthWestern Iranian languages. The Kurds are known to be an Iranic people because of close linguistic and cultural ties with other Iranians. The Kurds are also known to be descendants of the Medes, according to many scholars.

Somewhere along those lines. Saying that Kurds are an "Iranian ethnic group" is is vague, confusing, and somewhat mis-leading. What I wrote is a bit more clear and I wrote why they are considered an Iranic people with the sentences supporting it. Notice how I also said a language known as Kurdish. I do not know on what insane consensus that people decided it should be "Kurdish language(s)." Kurdish is one language which is mainly based of two dialects, that are spoken by almost all Kurds. Those two dialects are Kurmanji and Sorani, both of which are highly similar. All Kurds regard their language as one. I am a Kurdish Sorani speaker and I can understand a Kurmanji speaker perfectly. Kurds in Turkey, Syria, and Half of Iraq speak Kurmanji. Then the other Half of Iraqi Kurdistan speak Sorani, with Kurds in Iran speaking Kurdish Sorani as well. There are also a few other dialects such as Hawrami which is spoken by about 10% of Kurds. Nonetheless, the Kurdish language is one language with 2 main dialects, both of which are highly similar to each other.
