We must make sure everyone knows we are having none of it, shame any on our side who try and pretend there's something to this swill, and blanket 'news' outlets who try and peddle these lies with angry protests and threats of boycott --- anything short of actual threats of lethal violence.
The time for this sort of crap is over. They cannot ruin our leaders without our help, and we need to get this through our collective heads. Well-meaning, good-hearted people who tend to the left need to learn not to allow their better natures to be taken advantage of by vicious scum on the right, and splinterest wreckers on the far left, who enlist them in their charges against figures of the center left, by exhorting them to 'be consistent' and telling them 'don't be hypocrites'. The proper response to attempts at this is a hearty "Fuck off! Nobody cares what a rancid piece of dogshit like you thinks!" Or words to that effect....
Only attack the enemy, the christo-fascist right.
Never, ever, attack people who are on your side.
If you want one quick reason why the right wing wields power well out of proportion to the popularity of its policies, it is that they adhere to this rule, and we on the left do not.
There are a damned sight more of us than there are of them.
"Defeat of a dangerous enemy is something to be for."
