The stand nobody else takes is heavy for a week and light for the rest of your life.

Standing alone is heaviest at the start, while the room is still deciding and you have no company in it. That weight is real but short, because attention moves on quickly and what remains is the fact that you did it. What you carry afterwards is lighter than what you would have carried by staying quiet, which tends to be a low weight with no end date.

If there is something you know you should say, plan the first sentence and nothing else. Say it once, without heat, and let the silence sit. You do not have to win the moment to have taken the stand.
