Were the Capitol Riots comparable to 9/11?

I voted yes.  While the Capitol Riots obviously were in no way comparable to 9/11 in terms of lives lost and physical destruction, they represented a greater threat to the continued existence of the United States as we know it than 9/11 did.

It was a failed coup by a bunch of right-wing riff raff. 

Given that this is the United States we're talking about, I would say a "failed coup" is serious enough to make it comparable to 9/11.  Not in deaths and physical destruction, of course, but they are not the only measures of seriousness.
