You're against someone being open when they disagree with something, whether or not their position is valid?
That's a little ridiculous. Being Taoist in withdrawal from conflict is one thing, but being a responsible member of a group is another.
Jacques appears to take a view that disagreement (or "picking battles") is tantamount to a fist fight, which obviously should be avoided. But, I think the OP and others discussing here rather think of of it as merely a difference of opinion, to be noted and moved past. In that sense, "avoiding disagreement" is not helpful because they are not noted, but buried.
