The thing about social media is that if after election Trump would turn out to be the best president in our history. Instead of you, someone else would now cited the post that they said that in November.
The truth is, no one knew at the time. People had their theories, some were proved right, some were proven wrong.
The people who you were responding to are example that your opinion was just one of many. There was hope that perhaps Trump's ego would motivate him to be better than previous presidents. Sadly that didn't happen.
