I don't think the definition of "McCarthyism" is as narrow as you define it. I used that word because I though the analogy was appropriate and illustrated well what I was trying to express. Accepted definitions do not tie it to the use of government force, see e.g. "the practice of making unfair allegations or using unfair investigative techniques, especially in order to restrict dissent or political criticism." from http://www.dictionary.com/browse/mccarthyism?s=t
Words mean things. In the same way that people aren't being "lynched" when dozens of other people berate them online, calls to divest from bigots and their enablers don't constitute "McCarthyism".
Words mean different things depending on the context. And analogy and hyperbole are valid tools for expressing ideas. Now "lynching" would definitely be a bad analogy and way too much hyperbole, but "mccarthyism" was appropriate to illustrate what I was trying to say. At the time people lost ability to be employed because of their political views. You seem to be calling for boycotting anyone who voted or supported Trump in this election because they are bigots. And that is a logical jump I cannot agree with as I tried to explain above. Clearly some people voted for him because maintaining status quo was less acceptable than getting over the things he said. I do think that we would have to get off the high horse of moral superiority and try to understand what happened if we want to avoid surprises like this in the future.
