It's the same thing whether on like FB or IRL (in this case my mom) whenever I make an assertion about fake news or anything related the other side will either resort to:
A. Passive aggressive name calling or B. "Oh you just think you know Everything..." type of response
Any yall feel me on this one?
Yep. If you want to really have fun, dig deep in their preferred news sources. Follow all links back to primary source if possible (great if it lands on a government site).
Quite frequently, when you track back to the primary source, you can show them their own preferred news source is misquoting, taking quotes out of context, using outdated/ superseded information, or was later debunked by other parts of their favorite news sources. best case scenario you can show them their preferred news sources are outright lying about what the primary source says. Or you will find 2 different preferred news sources reporting two different "fact sets" on the same thing, from the same sources.
Then they get pissed and stop talking to you, generally after becoming extremely verbally abusive.
