I have some family members who are similar. In the past, I would be able to help talk people through their conspiracy theories to come to a logical conclusion that what they were hearing was too big, too harmful, or otherwise incapable of accomplishing anything to actually be true. That approach is becoming harder the bigger this becomes.
