That "editorial" is both ironic and hypocritical. Because it almost bursts of hate of "the left" and tries to convince you that it's okay to hate the left because they already hate you. But at least your own hate is justified and right, since their hate came first and you just hate them back accordingly. A prime example of an attempt in demonizing "the enemy".
You could very well replace every mention of "the left" in that "editorial" with "the right" and post it on a far-left message board and would get a lot of applause for it. Except that it wasn't posted on a far-left site, but a far-right site.
The editorial then ends on a very scary note (at least for my people like me) since it argues that armed battle with "the left" is inevitable and that "the left" will be defeated. I'd consider that as a threat.
I guess when right-wing loons send death threats to left-wing politicians (and they surely do, you can believe me that), they do it with the conviction that their actions are justified because "the left" hates them. And they arrived at that conclusion because of "editorials" like that.
