I can see what you’re trying to say here - don’t get caught up in the noise, but work to change the signal. I get that and agree it’s important. But I also see no reason to not oppose stuff like this - publicly and vocally:
Part of our modern political system (and this goes back to Habermas, yeah - public sphere theory) isn’t just voting or working within the party system (going door to door, phone banking, etc), but it’s engaging in public discourse with others. I’m not sure that just ignoring rhetoric like this helps us to steer the country away from this brink of really serious violence. You may not see it or feel it, but lots of people do and they deserve to hear that we support them, care about their well being, and want them to feel safe in this country. If those who enact legislation do not hear us BETWEEN elections, then they won’t know that we oppose such dangerous views.
