I think it is important to bring up this issues during preparations for the training in order to clarify mutual expectations. I am not prepared to keep quiet, on account of “loyalty” to the team, about something I consider unjust or something I am explicitly against. For me, team loyalty primarily means being able to publicly express our disagreements without worrying about “how this will look to the group”. It will look authentic. This authenticity – being who we really are, without pretence – is what builds trust, and the trust of the group is a precondition for working with them.
