What is "treasure in heaven"?, page-34

If you believe this to be true why do Jehovah's Witnesses only criticise and don't take a stand against injustice.

Whereu, history tells a different story.. The mainline religions, both Catholic and Protestant, compromised woefully in paying homage to Nazism, idolizing the führer, saluting his swastika flag, and blessing his troops as they sallied forth to slaughter their fellow believers in neighboring nations. So-called Christians of all faiths—but not Jehovah’s Witnesses—were caught up in the patriotic fervor. The book Mothers in the Fatherland reported: “[Jehovah’s Witnesses] were sent to concentration camps, a thousand of them were executed, and another thousand died between 1933 and 1945. . . . Catholics and Protestants heard their clergy urge them to cooperate with Hitler. If they resisted, they did so against orders from both church and state.” How bloodguilty both Church and State became!—Jeremiah 2:34.
The irony of the situation is that the Witnesses are recognized in most countries as honest, clean-living citizens, exemplary in upholding law and order. (Romans 13:1-7) Yet they are often persecuted. Why? Since worship belongs exclusively to Jehovah, they refrain from bowing to representations of the State or hailing them. (Deuteronomy 4:23, 24; 5:8-10; 6:13-15)
Whereu if everyone took the same stand there would be no war.
