I think I am beginning to see the primary difficulty in discussing things with some people on this website. They don't freakin read the material which they ought to be reading.
Again, She had a concussion back in 2012. Expert medical opinion thinks it damaged a nerve that controls her right eye's orientation.
There have been stories and videos about this. Apparently you weren't reading them because you were looking for more dirt on Trump.
She's hiding the effects of a concussion. Even ABC news (and others) acknowledged that she had a concussion back in 2012.
Nerve damage causing a Nystagmus is a possibility but it is not a seizure.
I probably shouldn't even go off on the 'problem discussing...' point you made, but it seems the problem you are having is when people don't believe the underlying premise you present. You want a total agreement, not a discussion.
And it isn't exactly helping Hillary to point out that there is a greater chance the Nystagmus is caused by alcoholism versus a medical condition she can't control because the former is both a medical condition and a statement on her judgment, while the latter is just a medical condition she can't control.
I still believe, from her history, that alcoholism is a greater possibility here. Yes, she had a concussion, but alcoholism would explain a lot more of her symptoms (including coughing), it is much more common and likely, and it is a statement about her continued judgment.
