.. and is it right, is the question behind the question.
This obviously is not right. It is not healthy democratic spirit to allow no criticism. In an open, fair, dynamic and progressive democratic state, it is the right of the people to criticise their leaders for whatever reason they may see it right. The well-established fact is the leaders and their governments need the voice of their people, and among them, the best of the critics, to guide them along, to formulate policy initiatives and advance their programs into action.
Mr Donal Trump has earned himself a reputation of a powerful president, capable of bold, clear but highly controversial policies stands, and this creates a big personality. Donald Trumps has come stand for America! Whoever criticises America criticises Trump!
In my opinion, whoever criticises Trump for good reason does a great favour to America.
