When you don't like what somebody says, the easiest way to discredit them is to stigmatize them and make it appear that they don't have any thing of value to offer.
The Germans did it in WW2, they even made Jews, Gays and Gypsies wear stars on their clothing. That way everybody would know before getting to know a person that there was something 'wrong' with that person.
The Bush administration does it (and denies that it does) with Arabs, Muslims and anybody different.
Police do it with profiling.
Now we have a local prominent person who feels it necessary to silence people who question authority.
WHY?
Well, once you become part of the establishment, you don't want your authority questioned. It becomes an issue of control.
Isn't that provocative ?
