What I'm getting at is two-fold. First, I am absolutely not (well, now that it's in the past, it should be "was absolutely not") trying to undermine the process to hold a president accountable. Note that I replaced the word "the" from your original post with "a", because Trump is not special in that sense as far as I'm concerned. My views on this would apply to any president, of any party, whether I liked them or not.
To be specific about that, what I'm really saying is that if a president has done something worthy of conviction after being impeached, then as sad and unfortunate as that may be, that is what should happen.
Also, the way your question was phrased leads me to infer that in your opinion, he's guilty, and he just needs to be held accountable. I also believe that you believe that I know he's guilty, but just don't want that to happen in the case of Trump. Refer to what I've already written to show you that I disagree with that, 100%.
The impeachment was the process that charged Trump with actions that were supposed to be, from the Democrat leadership's point of view, and apparently yours as well, with the high crimes or misdemeanors that you feel he's committed. Unfortunately for you and those who agree with you, justice requires some proof of an actual crime, and once the Senate conducted a trial, the case fell apart. In simpler words, they could not prove what they charged him with.
The second point is about the meme itself. I think very soon we will see that there is a provable case against people like Stzrok and Page, Brennan Clapper, Rice, Comey, McCabe, and even Biden, and possibly president Obama (although I doubt he'll ever be charged) that they attempted to stage what is the equivalent of a coup to prevent Trump from being elected, and once he was in office, to get rid of him. Sorry my friend, but that's treason. We have a process in place to remove a president, and that failed.
So, just not liking him, and believing falsely that he committed crimes because you want him to have committed those crimes, and also believing that most of America agrees with you (aka false consensus effect) is not sufficient grounds to prevent, or remove an individual from the presidency.
