Lol enough with the sophistry. The first Wikipedia article you linked to had numerous references to Islamic and Umayyad links with the Yazidis, including the formation of the religion as it exists. When you found that out, you decided to link to a second article and draw your own conclusions from it. But, even the second article shows that the Yazidis had Islamic links. Shaykh 'Adi ibn Musafir is a Sufi, after all. How can one say unequivocally that the Yazidi faith has no links to Islam?
I didn't find any article, it is all in the Wiki, you can "find" it by clicking it. You told me even that Wiki page says that it started during the Umayyad period by some guy, I simply clicked on his name, the page came up said nothing about Islam. It said he is a Yazidi. Not a founder or someone like that. It shouldn't be too hard to comprehend this, right? I didn't write the Wiki articles, I am drawing conclusions from what it is written there.
In other words, the term "Yazdanism" was completely made up by some Kurdish nationalist.
What? He is not a Kurdish nationalist, he is a famous author has produced several books about Kurds. Just because you didn't like his idea, he does not suddenly become a nationalist. The person whom you just called is holding a PhD degree and had given lectures in the US. Before bullshitting about someone, make sure you are better than him in his profession.
He even describes it as an "Aryan" belief system as opposed to "Semitic.
Yes, Kurds are not semitic people. They are a people of Iran. Guess where Aryan" comes from.
your own beliefs are based on myths made up for the purpose of nation-building.
Again, before bullshitting about someone, first get to know them. I am not Kurdish or Kurdish nationalists. There aren't "my own beliefs", but rather the people who studied the subject. Whether you like them or not, is completely another story -which we are not interested in, at all. You first dismissed Wikipedia by saying that it is not a source, now you dismiss the person who studied it. I can't take this anymore seriously.
For someone who spends so much time bashing Muslims for their beliefs, it is ironic that your own core beliefs are demonstrably falsifiable.
I'll take you serious sometime when you learn not to bullshit about people before knowing them, at least roughly.
I rest my case. Yazidisim, whose roots can be traced back to Yazdanism, is an ancient faith.
Thank you for your contribution. Have a nice day.
