The Ministry of Propaganda (i.e. the "Mainstream Newsmedia") will make short work of any "protesters". When the Propaganda Agents get through with them, they'll be "dangerous radicals" or psychotics or neo-Nazis or whatever works to discredit them.
And if the Propaganda Machine doesn't silence them, they can always be prosecuted for somethingorother--or sued for everything they've got--or locked up as "mental defectives"--or shipped off to the gulag--or simply made to "disappear".
My senator wouldn’t listen to his constituent if 99.9% of them called and faxed. He would vote how he wanted to and tell them how dumb they were for not wanting him to vote that way...and still he gets re-elected.
