I prefer freedom of speech and would defend anyone's right, including 'uncivil'  Sid Schwab's right to 'speak his mind'. I would not get so angry or hot-headed so as to 'block' or 'silence' his right. I do expect the same from him and you and all other Americans. With the exception of certain  college campuses,  where political correctness has taken a very fascist turn to the left, most places in America are still free.   If Trump were a dictator as some seem to infer, why did he legally proceed through the court system on his 'travel ban'?  He could have just    ignored the 9th District Court. A dictator certainly would have.

 Dissent has fizzled out because most of the protesters realize their folly and   have short attention spans, not because Trump stopped any of them.  If you mean un-civil as in "violence and destruction of property", then yes, that should be prosecuted  and punished.
