Let’s assume it’s a difficult decision. I can’t say that it was for Kaepernick because I don’t know him and certainly not his convictions. I know what he says and can choose to take him at his word or not. For me personally, to do something so extreme for a “cause” would have been exceedingly difficult. I can imagine taking this particular action in any scenario that exists today, but that’s my belief system and views.
But if it IS something you struggle with, it is completely rational and logical to not expect it to happen the moment you feel “injustice.” It might be something you contemplate, feel strongly about, but struggle finding the “courage.” I am not labeling Kap or anyone doing this as courageous because only they know their hearts and true motives. But I would offer an example that would illustrate what I am trying to say.
Many people have been raised in a Christian church. They might be their every Sunday, or even every time the “doors are open.” They have listened to 100s of sermons, and figured out at some point what they believe they should do. But for many people, it was years and years before they truly had a conversion experience where they”became a Christian,” as believers in Bible-based denominations believe. I suppose the same question you ask would apply to them. And before I get lambasted, I am NOT comparing the NFL situation with Christianity! Just offering an example of a delayed demonstration of conviction.
