I am a firm believer in singing what you like and apologizing for any offense..unless it is really really bad, in which case I would do folk surgery on it or not sing it. I also now try to take out specific anti-British words, like "if the color we must wear is England's cruel red" and making a substitution, which I don't like doing, because I do not like altering songs, but nevertheless...Just a disclaimer that you do not support violence in any form or whatever your beliefs are. I got scolded for singing some rebel song once for fear of inciting a riot or whatever and really had not connected them to incitefullness, at least in Seattle. But I absolutely positively do not believe you need a DNA connection or cultural connection to sing any song. You might lose 92% of the meaning, but maybe whoever you sing it to will get something else out of it. I also tend to be one who doesn't really listen to words too much of a song and others differ...mg
