I'm finding it difficult to see how a Trump voter can complain about tone. Trump himself is usually toxic and abrasive, and relies heavily on petty insults with the eloquence usually found on grade school playgrounds. His followers proudly wore "fuck your feelings" on their clothing, and that seems to have been their operational philosophy ("cucks! snowflakes! get out of your safe spaces!") before they realized how much the rest of the country hated them. Now, ironically, they complain about insults and not being accepted.
With all that in mind, is it any surprise people on the Left treat Trump with zero respect? And can you not understand how ridiculous it is to demand that respect when respect has not been given by your side. From the president on down, there has been no grace, no diplomacy, no kindness. This is a classic "remove the log in your own eye before complaining about the mote in another's" situation.
And that's without getting into how this administration is the most corrupt in modern American history. Perhaps the most corrupt ever in our nation. And is intent on doing as much looting & damage as possible before they're finally kicked out. Difficult to treat someone with respect when they're behaving in such a reprehensible fashion.
