Just to refresh memories, the assassination attempts on Trump were done by people with right wing backgrounds.
I just got back from a peaceful "No Kings" protest in Illinois, and aright wing chud waving a Trump flag swerved his oversized SUV right onto the shoulder in front of some protesters. This is not a both sides problem.
The comment in question pulled a "both sides" on an issue that is beyond overwhelmingly coming from the right side of the spectrum.
Two Democratic state Senators were just brutally attacked, and at least one killed. That's not the time for Democrats to introspect, it's a time to be outraged.
Drawing some kind of similarity between internet commenters wishing a conservative assassin had succeeded in killing Trump, and a (almost certainly) right wing chud actually assassinating two Democratic Senators is bullshit. Political violence in this country comes almost entirely one direction. Pretending otherwise just blunts that reality and makes future attacks all the more likely.
