First i am not a racist second i have no idea about my DNA so now to the point i wanted to make.
I can just laugh when i hear a Genghis khan descendants to call themselves persians i mean come on are you freaking ashamed of your past that you need to take another identity, oh and other is the iranians who call themselves same as mongols
I am never going to be accepted as Timur's or Viking descendants so why should i let anyone else let to do so because i am shure that the ancestors wouldn't wanted.
But besides that i know that there is a big variation in skin-hair-eyes color, but come on do you really think that if you say to me that a chinese looking guy or an ethiopian is a persian just because he speaks persian?
Now i dont mean that i will make an holy crusade or something, actually i can treat you as a brother regardless the ethnicity and i will stand against my "race" if they do some shit but telling that we have the same grandfather shows me just how much credible you are. Be who you really are for truth will always prevail.
Thanks and Peace to all of you.
