Political discourse has always been a high-contact sport played without helmets or padding. Today, it has become more like ultimate fighting with machetes and without rules or referees. Maybe there really never was a time when people considered those with different political opinions kindly as the "loyal opposition." But these days, people who see things differently are often thought of as implacable enemies. Folks do not think that their political opposites are just mistaken. Many now think of them as demonically and irredeemably evil.
