Your post reminds me that Menuhin said about his mother: this woman of strong character had chosen his first name (Yehudi, as you know, means Jew in Hebrew) for he never forgets his origines.He also said: "I am convinced that music can bring people together and heal."
I think Menuhin remained faithful throughout his life to this belief and this humanism that he has stubbornly opposed to the intolerance of all kinds (for example after the war he defended Wilhelm Furtwängler, who was accused of having collaborated with the Nazis and did a concert in Berlin with him).
This reminds me also this great quote from Voltaire:"I do not agree with what you have to say, but I'll defend to the death your right to say it."
Faced with intolerance, bigotry, injustice, there is no compromise possible. Never.
That's what makes human dignity.
