Jim,You undoubtedly have a deep love of folk song,I respect and recognise
that.
Therein lies the problem,you have formed your views on what it means to you.Those views and opinions are very important to you.
You are very protective of them,which can make your counter replies to those who challenge them aggressive and often insulting,sadly a tit for tat quarrel then breaks out.
Neither party wins an argument on those lines and loses dignity and respect.
Swallow pride and agree to differ,the next time someone pokes the fire, ignore them.
