That's not “the one time” such agreement has occurred.
Here's the bills she's cosponsored with Republicans:

> she calls back on something they don't agree on (and refuses to work with them because of it).
Sure, complicity in a violent, deadly attack on one's workplace (even when it isn't the national Capitol and part of a coup attempt) is the kind of thing most people would just brush off and not let get in the way of working with people: actions have no consequences whatsoever.
- It encourages others to do the same; someone doesn't agree with you on an important issue (pro life?) - just refuse to work with them. This furthers the divide in US politics and is (imo) an overall negative.
- It hurts her own cause by removing support she already has - is this what a representative is supposed to do?
Although true this is hyperbole. We're not talking about the "deadly protests" for BLM so why did the capitol protest become a "deadly insurrection"?
A lot of people are calling for Donald Trump to go to prison/etc; does that mean (if he was still president) he should stop talking to anyone saying so?
I think your fist point is making this into something more than it really is.
