One of my grandfathers was a committed communinst. He was born in abject poverty in a tiny village. The socialist government radically improved his conditions and it made him loyal for life. Sadly he died when I was in primary school so I never got to talk to him about it. I just know what my parents told me about him.
The grandparents on the other side of the family are sadly virurently racist anticommunists. Grandmother proudly told me how her family hosted a nazi officer during the war. Cut contact with those assholes a long time ago and it improved my life significantly.
