Her having classified info...and sending classified info...is fine. It was part of her job.
The problem was, if that information was stored/sent from a non-secure system, that is a problem. That goes back to protecting the integrity of secure information. Just a few weeks ago, we had a midshipman prosecuted and sentenced to a year in jail for taking a selfie at work, to send to his daughter (young, 6 or 7). He was standing in the engine room....secured information zone. There was no machinery behind him...just a wall with a sign that said "wear your ear protection". However he was in a secure information zone.
That picture, as innocent as it is, is putting him in jail for a year, and is going to have him discharged from the Navy. This is an honest mistake. No malice. No deceit. When asked about it, he fessed up.
You'll notice that isn't the case with H.Clinton. There wasn't malice. But there was certainly deceit.

so far we know that:
(a) the FBI could not bring criminal charges against Hillary for her email usage
(b) the State Department allowed her to use a privately run server for official State business (the last of her kind as they changed the law to prevent this in the future)
(c) the "new" emails most likely contain nothing to do with Hillary, it's literally Comey trying to put his thumb on the scales and illegally influence the election a week before it happens
so given (a) and (b), at least half of your argument is invalid due to the practice being legal at the time it occurred, and the fact that despite an investigation no crime could be found to have been committed.
certainly there is a level of deceit going on, but most reasonable people believe there to be about an average amount of deceit given Hillary's position and career. the big problem as i (and it seems, most people) see it is that because Hillary has been vilified for 25+ years, the perception is that she is somehow more dishonest than anyone who has ever worked in government, and i don't think that argument holds much water either.
