I think we're arguing on a very narrow line. I know your views, I just have a problem with seven players refusing to take the field with not a word out of the mouths of a single one of them. Not a word.
To me, protest needs to be very clear, both the action, and the reasons for it. They may well have explained it to the club, coach, team mates etc., but none of them exist without a paying public (either by attendance or eyeballs). Without that very clear explanation, their protest, to me and many others, is invalid.
If they'd spoken, I agree with your standing up for the principle.
And I don't believe for one second that there isn't some resentment from those who played and who've had to front up to the media week after week.
Strangely, I had a good chat with the wife of one of our players, a woman who has worked in the game, and she believed that if it had been handled with programs and education etc. that they probably would have played. Yes the club handled it badly but there was also shock at the boycott.
