Alex hammered his Sandy Hook conspiracy theory to the point of being sued for defamation, and losing (https://duckduckgo.com/?t=ffab&q=alex+jones+sandy+hook+lawsu...). Families were forced to move multiple times, unable to visit graves. When the families faced hardship, Alex doubled down on his claims. He never took a moment to ask his supporters to back off or seek a calmer resolution.
Whereas Bernie immediately denounced the shooter and reached out to Steve Scalise. Steve does not blame Bernie for having a deranged fan (https://www.newsweek.com/steve-scalise-shooting-bernie-sande...). Bernie did not imply Steve deserved to be harassed or shot. He has, in fact, asked his supporters to back off (https://www.rollingstone.com/politics/politics-news/bernie-s...).
These two things are obviously not equivalent.
