Damn, I'm glad the closest I have to deal with regard to that is my Step-dad, but fortunately I don't see him that much and can distract him by talking about music.The only issue I've had with the local permanent site is that one of them once pulled out in front of me as I was driving up the road next to the site
I grew up in what seems like the exact opposite of your family, funnily enough. I grew up in a household where racist and xenophobic views were drilled into me constantly and luckily I quickly (in my early teens) realised these were not how I felt at all. I still held on to some biases towards people (based around class, social welfare, even gender), that I now find appalling, until my mid 20s due to working in toxic environments with terrible people and getting a lot of my information from newspapers and nothing else. Luckily I was able to take a step back and challenge these biases and eventually change them.
My parents, however, still hold some racist views and believe a lot of what is printed in The Sun or The Daily Mail when it comes to race and immigration. Pretty much every time I visit them I end up expressing my disgust at something they have said. Brexit only served to make things worse in this regard.
I have however worked with far too many people who would get on great with your parents.
