It is stated that Sharingan makes one close to invulnerable to Genjutsu. You're right, he said if they open their eyes, they're finished. He never said anything about himself being at risk. So either A) He didn't care or B) He didn't know. He assumed Itachi was heightened. Therefore his Genjutsu would. But that doesn't mean he knew the Genjutsu would affect him to the point he couldn't break free, someone who possessed the Sharingan. So he was confident enough to look into Itachi's eyes. FACT.

What chapter did Kakashi go to Gai? If I remember correctly, Kakashi didn't ask a single thing, Gai was talking to Asuma and Kurenai while Kakashi was incapacitated and Gai had him over his shoulder. Gai literally stated he invented that way of fighting to fight Kakashi. Therefore, it's highly unlikely that Kakashi never witnessed it.

And yes it is a fact. If Kakashi knew it could have affected him, he wouldn't have looked. He's not an idiot like you seem to suggest.
