I think it is arrogant to change what has been around for hundreds of years . . ./

Perhaps you could say something like, "I personally don't like changing old songs . . ." Calling other people arrogant is, whether you want it to be or not, an attempt to get other people to follow your rules. I you said "I think it is arrogant", but that doesn't really matter. If you want people to understand you and not jump to conclusions about what you mean, you might consider your choice of words more carefully.

You see, I don't think it's arrogant. I don't think the folk process ever stopped, and I think that updating traditional songs for modern listeners is part of the process. When you use words like 'arrogant' you are also saying the other person is wrong.

Just out of curiosity, why are you so sure our paths will never cross in person? And why are you so sure that you would dislike what the ways in which I play traditional music? It starts to sound like the scholarship is more important than the musical and lyrical quality of the song.
