Oh please, have some courage and own up to the fact that both sides of the spectrum are just as capable and as likely to throw acronyms and barbs at each other. I read taunts from the left such as Nazi, fascist denier, mouth breather, flat earther, conbot etc. It doesn't give the right any social license to respond in kind either. 

Myself and others have called you out on this, and your response is a grade school "he/she started it". 

As for the left "biting their tongues and being ultra polite". I find that laughable given that multiple Canadian and US universities/colleges have cancelled or refused right of center speakers on their campus because they couldn't afford or guarantee their safety.
