I guess what you are looking for is this passage by Martin Niemoller, a German religious leader before World War II:
In Germany,
At first they came for the producer of * * *, but I didn't speak-because I'm not a producer of * * *;
Then they came after the Jews, and I didn't speak-because I'm not Jewish;
Later, they came after union members, and I didn't speak-because I'm not a union member;
After that, they came after Catholics, and I didn't speak-because I was a Protestant;
Finally, they came to me, but no one stood up for me anymore.
Martini Mora
Martini Mora is a priest. The original text is now engraved on the Holocaust Monument in Boston, USA.
Here, if you are a student or just graduated, it is strongly recommended that you recite it. On some occasions, if you can recite the original English, you will win honor for the people of China and our mainland. If you can quote in the speech contest and speak fluently and generously, you will often get applause and get extra points!
In Germany, they first came after communists,
I didn't speak, because I'm not a communist party member.
Then they came after the Jews,
I didn't speak because I'm not Jewish.
Then they went after union members,
I didn't speak because I'm not a member of the trade union.
Then they went after Catholics,
I didn't speak because I was a Protestant.
Then they came to me,
But by that time, no one had come forward to speak.
Pastor Martin Niemoller, 1945
