Against is different from protest, which is a protection for rights; it is a very straightforward action for “I don’t agree”. Thus, it’s rejection-driven, to establish one’s own boundaries of belief, rather than affirmation-driven.
Practically, it should be easier to act, rather than just saying. However, there are rare people who dare to do it. Mostly, people express their complicated emotions about something they disagree with, but their actions still confirm what they disagree. Such a situation is referred to as a complaint.
Theoretically, if an “against” is situated in a value behind the behaviour that is opposite to your belief, it happens naturally to protect your belief. In such a circumstance, belief is above.
As an “against” is very small, even subtle, it generally won’t significantly alter the overall structure. To some extent, it is a “useless against”. However, when an individual takes any small steps, it shows their attitude, and they do it. Then, any feedback from such an action will be a unique spiritual capital for oneself. They will slowly learn how far their belief can reach.
