Yeah basically we agree on 99.99% on everything and her doubts are well-informed but whenever we talk about that we have a slight polite disagreement and it's getting really tiring. We don't talk about the US election at all because we're European. Should I cut all ties with all my family and friends and neighbours and colleagues over this disagreement? The rest of my family are all members of the CPC so they're pretty cool.
Unfortunate but the only solution in this instance is to give her the Ol’ Yeller treatment.
One thing would be if she was a standard lib but your own sister? A revisionist? This hurts and only the sweet release of death, for her, will bring you tranquility
