Edit:
Aunt and I talked politics for over 30 years, whenever we did talk. We were both anti-Republican ( Bush Family ) but she was far more pro-Dem than I. Long story short, Cuomo resigning was a big wake up call. I had told her about the nursing homes, but she did not accept it was possible. After her second shot, I told her they would come up with a new variant before Christmas. She blew up my phone on MORONIC day. The icing on the cake was Fredo going down. She, for once, sees all the connections. She is nervous about the side effects from the vax and actively looking into remedies. She already knows about Ivermectic and Hydroxychloroquine.
"I dunno, I just think they're lying"
I find a relaxed, curious but skeptical attitude to be more effective than oppositional debate.
Different techniques work with different people but you're right, I was never confrontational with her, just passing information. I actually stayed out of the vax debate, only telling her 'there is no way in hell I would get it.'
