The left is an entire basket of deplorables!
It is a standard tactic of the Left to strike first, accusing their opponents of doing what crimes or vile actions they, themselves, are doing. It puts their opponents on the defensive, and counter accusations of impropriety by the Left only appear to be counterstrikes, and not justified complaints, so they can be dismissed easily in the media unless there is some serious evidence, and sometimes even then. I have seen others use the tactic as well.
