I know where your coming from. My parents feel right down the racist conspiracy theory rabbit hole during Brexit and COVID. I was working in the hospital watching people and colleagues die regularly and my dad was telling me it’s just flu and all a hoax to scare people, they convinced my 90 year old grandma to not get the vaccine. We had a lot of fights. Eventually after a lot of reflecting I decided that having a relationship with my family was more important than winning an argument so now we just have a selection of topics I refuse to engage with, just say let’s move on and change the topic. I found it really hard to see the people who raised me fall into racist rhetoric and conspiracy theory thinking, these people taught me to be a good person and now have some glaring holes in their compassion for others. I struggled with that for a long time.
