Politics is violence. Worse, politics is usually aggression.
A blanket condemnation of political violence while still doing politics is a denial of reality. It's like calling for people to reject round circles or wet water. I understand why they have to say it, but really...
Politics is violence!
Its violence is usually camouflaged behind other words. Words like "democracy" or "laws". The threats are called something else, too. But politics is violence.
Yes, reject political violence by rejecting politics! Otherwise, you're just making ridiculous noise with your face or laying out a string of absurd words with your fingers.
Politics doesn't improve anyone's character. It doesn't make society better. It's a cancer.
