Neutrality is an expensive option. When you see someone being wronged and fail to take the side of the one being wronged you reward the wrongdoer. Then the one who was wronged suffers more wrong by your lack of support.
If you care for two people and one of them wrongs the other, you must take the side of the one wronged. If you remain neutral you lose the affection and respect of the one who was wronged. If you do not remain neutral you only lose the affection of the wrongdoer. But you uphold what is right when you condemn the wrongdoer. Better that you lose the wrongdoer than the one wronged.
The Menninger brothers were famous psychiatrists who ran a wonderful world renowned clinic in Topeka, Kansas. I read remarks by one of them once when I was young about what he called the sin of apathy, which he described as the failure to take the right side when evil is done. He described the tendency to try to remain neutral and avoid taking sides as a very serious evil because it rewards evil. He was right. Neutrality is a wonderful reward to wrongdoers and only adds to the harm of the one who is wronged.
My good friend, Walter J. Hopp, wrote this a few years ago, as notes to his children from their father. They have a wise father. What should seem obvious is difficult for many well-intentioned people to follow. They believe that they are being “nice” by not taking sides. Instead, like the nations which did not stand up to Hitler initially, they enabled evil.
