Fanboy, fanboy, fanboy.
You didn't even post an argument, just a fact.
If you think Kakashi can beat Danzo, well you know how the rest goes, I've said it enough to you.
Bottom line is you are wrong, and have no arguments.
Also find me the manga page where KA needs eye contact. I may be mistaken but didn't Danzo keep that eye bandaged up the entire time? So how did he use it on Mifune? How was he planning on using it on Tobi?
And also, how would Kakashi even know not to make eye contact? He doesn't know what is underneath that bandage, so why would he not look at Danzo's eye + bandage? He knows literally nothing about Danzo's techniques, so nothing you say can save you in this argument.
