@shibao people are bloodthirsty and tribal because that is what millennia of selection created, those who did not behave so died - peace, civility, and republic are an exceptional state which require a very narrow set of conditions
those conditions are gone and so we return to a more martial and violent norm
the left have done sufficient violence and murder their power represents a threat to survival, the browns are a foreign hostile population
your ethics may have been fine in decades past, but we are well past any kind of civil society or social contract and in a factional slow burn race war and civil war and a color revolution by foreigners
