You pays your money, you takes your chances.
The key thing for you is not to take it personally.
If the NWBO longs are wrong, we'll pay by losing big money.
The question is, not so much whether the means are good, is whether the ends justify the means.
NWBO finds itself at war and in war institutions and governments both basically good or essentially bad, will do things that are dishonest, even evil to win.
The British and Americans in World War II did terrible things to defeat the Axis including the least of which was lying.
Wartime necessity.
The problem is, the Germans, the Japanese and the Soviets (who switched to the Allied side after Hitler betrayed them) did even worse things in their vein attempt to defeat their enemies. Given their twisted worldview, even the genocides of the Nazis went towards the fulfillment of their war aims rather than distracting from them.
Wartime necessity.
The difference?
The British and Americans were defending some form of democracy and cut the crap as soon as the war was won. They even rebuilt their defeated enemies.
The Germans, Japanese and Soviets were defending some form of autocracy and the Soviets, the only objectively evil power to survive, kept up the full measure of their brutality well after the war was won.
So whether NWBO's tactics are enough to push you away, really comes down to what you believe their motivations are.
