Do you think all the people on both sides are bad? You have Antifa and you have white supremacist, are they all bad people who should be jailed? Some of the protestors maybe left or right, but don’t belong to Antifa or white nationalists.
From what is reported in media, Antifa is much more than the right fringe. Antifa has more population, more media support and Antifa seems to win the street fight overwhelmingly.
Violence from any side is bad. Even if you think left is good, extreme leftists can still kill a moderate leftist
