What a stupide headline....Lost his Temper?? Or reacted with a statement of “common sense”.
Another manifestation of the liberal universal equivalence doctrine. The truth or lack thereof in your position nor the urgency of the issue makes no difference to the allowed vitriol level. All opinions are equally valid, therefore you may never communicate yours forcefully.
Now this might be confusing for you if you think about the double standard with which they judge their fellow travelers vs. conservatives, but you have to allow for the completely separate, but similar in principle Liberal corollary to the doctrine: If a liberal says something, even if they’re outraged, and even if the thing they’re outraged about is obviously bunk, or something they do themselves, no censure need be applied. Some rationalization can always be found for anything a liberal does.
