gosh, you even "sound " like Trump.;-)
It has noting to do with free speech. It has nothing to do with "left" or "right" or??
It has everything to do with effective & constructive speaking ability. any leader must have a decent command of the English language to start with. Tact and diplomacy and some finesse are critical for a leader of any nation. Being inflammatory,combative , and caustic verbal style is counterproductive.in the role of leadership. It might be interesting, and a novelty for a while.... but sensibility and good form are the order of leadership.
BUT if a nation doesn't mind an inarticulate, boorish, unsophisticated bully -with a personality disorder - as their leader......so be it.
