The linguistics of the radical wire up logic and self control to empathy to root society in core values and promote cooperation. The linguistics of all varieties of extremism wire up emotional indifference to fear (and sometimes logic without empathy). It is biologically impossible to make sound choices without using both logic and empathy in simultaneously, indeed, it becomes a form of slow-mo developmental brain damage that destroys both the connection of the individual to the best version of themselves and society itself. If a mechanic was miswiring a car you'd stop them, extremists (such as alt right) miswire the brain. It's a kind of short circuit that cuts out the most important and most highly evolved human ability - that of love. God gave it. Let's keep it.
