To emphasize this point:

First they came for the socialists, and I did not speak out—because I was not a socialist.

Then they came for the trade unionists, and I did not speak out—because I was not a trade unionist.

Then they came for the Jews, and I did not speak out—because I was not a Jew.

Then they came for me—and there was no one left to speak for me.

[A famous quote by a German after the Holocaust, lamenting his inaction during the Nazi regime.]

I think it is incredibly crass and craven to assert that one needs to be personally affected by an issue to speak out on it.
