Individually? Get involved. Become an Election Judge. Ensure that there's someone in the room besides an 85 year old who may not fully understand modern voting methods and rules, and an [insert any party here] zealot who may care more about maintaining partisan power than rigorously upholding election law. Also, write or call your local officials and representatives, personally if possible, and let them know, loud and clear, that you do not support grey area issues like vote harvesting or mail-in voting for major elections, and that having the support of you and your peers depends on them not supporting it either.

Culturally, help fight off the divided mentality we seem to have been stuck in for literally over a generation now. It's really not an "us" verses "them" country, no matter how much politics insist upon the contrary; we all just want to work, do well by our friends and neighbors, and provide for our families. Maybe even make the country/planet/etc a little bit better as we do so. "Life, Liberty, and the Pursuit of Happiness", right? Of course we have vastly different ideas on how to do those things. We're different people. But they're still the same basic goals. You want to take away those article's power to pit us against each other over it? Let it go and move on. Tell others to do the same. Yes, there are exceptions and extremists and griefers, and there will continue to be, but we have to stop treating them like they're the norm, and not us.
