Indeed, I didn't see any news reports of "liberals inciting violence." This one shooter was, by all accounts, a wacked-out liberal. The key word here being “wacked-out,” not liberal.

As to members of congress, collectively expressing empathy for a colleague has very little – and ought not – to do with being “bipartisan.” It’s easy to forget they are human beings, too, and reacted how we all would if a tragedy struck a colleague. That doesn’t mean we’ll henceforth agree with each other on all matters.
