The post is a jab about American folks who conflate the terms. I wasn't expecting people to take this as seriously as others have!
Although now that you mentioned it, I kinda sense that there could be something going on sometimes, especially on comments looking down on the working class supporting the Republicans, while refusing to acknowledge that they used to vote Democrats. Plenty of people worth their salt would tell anyone that it is because the working class felt abandoned after the outsourcing of jobs without offering alternatives. Unfortunately, a lot on the left, but more so on liberals, don't see this and keep calling the working class as dumb hicks. There are definitely folks who are too far gone and support fascists, but to caricaturise everyone in the demographic while a more plausible explanation is available seems tone deaf. It made me think that there could be an intentional wedge to create in-fighting for such deliberate nosing down.
