I think that my 'Guilty Pleasures' must be listening to all those songs that Bill D considers not to be folk.
As to the thread creep or secondary issue here-
Just start a thread on the forum using any title you choose. If Max asks you not to do it on that subject (which is indeed rare), then don't do it but don't take any notice of any other opinion. For the only opinion that matters is shown by the contributions to that thread. If the subject is not generally appreciated the thread will die of 'starvation'. Which is the very best criticism and the only effective method of dealing with an 'unsuitable' subject (or poster). If contributors keep posting to that thread to say how unsuitable the subject is and try to 'bully' their opinions on others, then they are defeating their own end and should start their own thread and open up their opinions to the same "effective method".
I would make a distinction to posts to existing threads, where the tone set by the originator of the thread should be respected.
