Your theory is full of flaws. My question; "Why didn't every Uchiha copy the MS if Kakashi could copy it?". Your response, (2) is Full of bullshit. Madara and Izuna both obtained the Mangekyou Sharingan by killing their friends. Do u think all the Uchihas who existed then wouldn't have noticed? Also, Madara met Itachi after a whole generation or two. That means Uchihas existed for at least several decades AFTER Madara was "killed" by Hashirama. See where you're wrong?
You also need to stop linking manga chapters that has nothing to do with this discussion. Adding useless source just makes u look desperate.
2a, the truth about Itachi was everything he told Sasuke.
2b, that Amaterasu implant was one use only. It wasn't permanent. Sasuke awakened his own MS after learning that Itachi was good all along. You need to completely read my post because I said this in my 1st post that Uchihas don't need to "kill" their closest comrades in order to get MS, witnessing/ feeling emotional trauma is enough.
2c, he's referring to Amaterasu. 2d, Madara said eye techniques, not the Dojutsu (MS). You're the one who corrected me and explained the difference between techniques of Dojutsu and the Dojutsu itself. 2e, everyone knows that, useless info.
2f, I don't see your point. Madara just states that his brother volunteered to give him his eyes. Like I said, not every Uchihas were stupid enough to not figure out that Madara had taken his brother's eyes and killed is friend in order to gain a new Sharingan.

, here. Madara says he killed his friends and took his brother's Sharingan to increase his own powers.
2g, useless info.
2h, useless info again. He was around in the Leaf until AFTER it was founded He had EMS much before that. He had MS before he founded the Leaf. Your own link says every Uchiha knew how he obtained his power... I honestly don't see your point.
2i, useless info.
2j, yep,
You must be registered for see links
here, a link that Madara himself states that Itachi murdered his friends thus proving my point of how Itachi obtained his MS. Itachi himself has stated this numerous times in the past.
3). Like I said, your theory and I disagree with it completely. Never in a manga did Kakashi copy a Kekkei Genkai technique and he stated himself that he can't. He isn't able to use Tsukiyomi, he uses Kamui and that's my proof. His MS has nothing to do with Itachi's MS.
4). Yeah, they do evolve and gain new abilities. I never denied it. Kakashi copying MS is far-fetched.
5). ROFL, why don't u prove urself by showing me exactly where a Sharingan has copied any Kekkei Genkai, please show me because YOU ARE the one who's handing out theories, not me. We've seen Sharingan copy common ninjutsu but never seen it copy a Kekkei Genkai. Show me proof of a Sharingan doing exactly what you said or your theory is just as irreverent as any other.
6). Every single person on this board knows one doesn't need to kill a friend to obtain the 3 tomoe Sharingan. WHy do u keep bringing it up? MS is different, it comes with a price and it has been stated in the manga more than once. Kill an ally to obtain higher power, lose sight unless u take a sibling's eye. This is why Uchihas are known to have a cursed history filled with bloodshed and violence. <-- That's fact. I'm sure everyone else who has read the manga knows this. See the difference? Ur making shit up meaning all of what u r trying to prove is a theory.
7). read up on the manga and learn some more stuff about Sharingan, then post ur theory because u obviously have no idea how the copy part of Sharingan works. Also, we dont have to provide any proof as u r the one stating ur opinion/ theory. Your theory is implausible and flawed, I don't agree with it and never will.
PS: I'm not arguing, just debating. And shade, i'm not the one who brought ur professionalism into this thread. U stated u know "a thing or two about Biology/ genetics" and I simply stated that u should also know that wikipedia is not a relevant source. Also, Wikileaks is different than Wikipedia and Narut-wiki, wrong again rofl. Search it up, do some research. I will astop trying to explain the obvious facts because u seem ignorant and only seem to believe what u post. As bitter as I might sound, i'm being truthful and if u don't like it, stop responding to me because u won't change my mind with ur oblivious theory.
My opinion; Kakashi obtained his MS during the time-skip. We'll find out if Kishi decides to tell us. His MS has nothing to do with Itachi's encounter.
