That's obviously a big question that political theorists can debate. I think I'd take it in a slightly different direction, which is to say that these are often actual threats against people's physical or psychological safety. There are all sorts of ways that we need to think about addressing this.
A report I co-wrote with Chris Tenove in 2020 gives a whole host of recommendations for how we can try to address these kinds of things so that we can continue to have a democracy and, hopefully, build on a democracy that has a diverse group of political candidates and representatives. I'd be happy to submit that report to the committee.
