So, again, there's a standard counter-argument that you also can't fight the power without aggressive suppression of speech supporting the status quo.

Also, in your statement is a buried assumption that the people happiest with the status quo are the ones most likely to be upset by speech from people challenging it. There is again a standard counter-argument to this, asserting that being very, very upset is part and parcel of "fighting the power," and the right to upset people is used mostly by cruel-minded supporters of the status quo as a means to amuse themselves by upsetting the agitators more or to goad them into violence that can be used as a pretext for state suppression.
