As a folk enthusiast and songwriter, I advocate for writing as many songs as possible without censorship and showing all sides and opinions.
It's great folklore and folk music. I used to love Sing Out! magazine because there were heated discussions about topical issues. I sing some
songs because they are diametrically opposed to my own ideology
but I believe they should be heard so people could understand
different points of view. I think a song like "The Unreconstructed
Rebel", or "Flag of Blue, White and Red" serve a purpose if it is presented in context and not as
a reflection of the singer. It has a historical purpose.
So, write as much as you want about Putin, Biden, Trump, Hitler,
Zilenskyy, Mussolini or whoever as long as it's an interesting and well-written song and it doesn't bother me. I might sing it in the context that I choose. I might even write a rebuttal.

Cancel Culture has no place in folk music AFAIC. (as far as I' concerned)
