London Old Man, here at Mudcat we have 2 types of threads: those about music (above "the line") and thos about non-musical topics (below the line, also known as BS). Normally, a thread will be started intentionally as being one or the other (for example, BS threads will often be lists if jokes, political discussion, etc). However, if the tread or the discussion it generates is deemed to be not of a musical nature (due to either its content or the discussion it generates) it can be moved to the BS section. An important point here is that it's not necessarily your fault for starting the thread; it could have good intentions, but certain people can't seem to play nice, so it gets moved to BS because of that. It doesn't help that lately a number of threads masquerading as music posts have been started but generated by-and-large less-than-musical responses.
Here's an interesting link discussing Seeger's opinion in the song and much of what I think you're going for: https://theconversation.com/the-misguided-attacks-on-this-land-is-your-land-121169
From that article comes this additional stanza Seeger would sometimes add:
This land is your land, but it once was my land
Before we sold you Manhattan Island
You pushed my nation to the reservation,
This land was stole by you from me.
