Although the Left are violent, on an individual basis, they are weak. One-on-one, they seldom can deal with their Right opponents, not that anyone should be naughty and fighting anyway (bad, bad, illegal etc.), but this is simply my professional observation from YouTube pondering and viewing. However, there may be a scientific explanation for this, that stronger, muscular men, tend to be more conservative, if not Right wing:

“Men with large upper bodies have a tendency to favour inequality in society and a limited redistribution of resources. This is the conclusion drawn by Professor Michael Bang Petersen and Associate Professor Lasse Laustsen from the Department of Political Science in a study published in the journal, Political Psychology. "The results challenge the belief that our political views are formed by logic and reason alone. Instead, our views seemingly reflect intuitions produced by a Stone Age mind," says Michael Bang Petersen. Modern man thinks with his caveman brain. The new study concerns humans, but takes a theoretical starting point in one of the most well-documented findings in the study of animals: Physical strength shapes the conflict behaviour of animals. If animals are larger and stronger than their rivals, they are prone to attempt to assert themselves in the struggle for status and resources. However, if they are weaker than their rivals, they are likely to withdraw from the conflict. According to the latest research results from Aarhus BSS, the same logic applies to modern men when they reason about political conflicts regarding the redistribution of resources in society.
