Riots as an excuse to let testosterone run rampant

While watching TV the other night, since my host family always has the news channels on (that have been exclusively reporting on topics involving the municiple elections), I became "arta" (maxed out) with the scenes of young males rioting throughout their own pueblo´s streets.
Although the news can´t be fully relied on in order to be completely informed, and of course, one must take their own initiative to view and read other information sources -- all the coverage of violence since the election results has shown specifically males committing harm to their society, their people. They say it is because they are "defending their vote." But can´t defending one´s vote be non in a non-violent, dialogue manner? YES. YES IT CAN!!!!
It has come to the point where these constant occurrences of cars being set on fire, people being stoned out of nowhere, homes being vandalized, billboards being torn down, rotundas being taken over by angry people threatening the environment with sticks and poles (all being committed mainly by men)--- have become an excuse to run rampant and destructively throughout the streets, letting out built-up and ideologized testosterone.
Police fill the rotundas (round-abouts) that are located on many popular, busy streets... but where have they been to prevent and to STOP this terrible and disgusting expression of "macho-ness"????
