Medicare for All is socialist. Public schools, roads, mail service, etc are socialist. Anything the government does to serve the people is socialist. Socialism is a scary word for Republicans. It is necessary for Republicans to use scary words to convince their base that they should remain loyal, because if they actually understood that they are voting against their own best interests they wouldn’t be Republicans. They have been taught that socialism is scary. 1%er owned news outlets have been telling them so for about 40 years now. So, if they are told someone is socialist, they don’t educate themselves to find out exactly what they are supposed to be afraid of. It’s a pretty shaky system and it’s amazing that people have fallen for it long enough for the country be in the condition it is, but they have.
