[I hear firing him is part of a cover up, a threat to the republic, that there was growing trust in Comey.]
Ah, an anecdote.  You'll excuse me if I don't believe an anecdote.
[do you think Comey was doing a good enough job not to be fired?]
Wow.  Do you value my opinion so much that it actually matters or is significant in regards to this topic?  No, you don't as you continue to maintain a position in direct disregard to what I wrote.  There is no point to asking my opinion unless you are fishing for some trolling material.
[I think the folks who called for him to step down or be fired, who are now upset that very thing actually happened, are being hypocritical]
Because rational, non-hypocritical people cannot be critical of Trump's timing, conduct, or inconsistency.  Yeah, no.  I'm going to have to disagree with you there and conclude I am wasting my time as you again disregard the problem with your position even after I clearly elucidated it and brought it your attention again.
