Certain fringe groups feel that they are entitled to use violence to disrupt political gatherings whose aims they disagree with. This is contrary to civil discourse and a threat to democracy.
I propose that the political party supported by any group which resorts to campaigns of violence or intimidation in order to quell an opposing candidate's message shall forfeit 10% of the votes cast for their candidate in the ensuing election.
Votes forfeited for this reason shall not be transferred to any other candidate - they shall simply be as if not cast.
