[DonRotolo]

One thing that might help is to find out what problem this group is trying to solve.

Just like in building a robot, you must first identify the problem. Once that's done, there can be several ways to solve the problem, some clearly better than others.

If the solution will cause new problems, perhaps a different solution can be crafted to avoid both the old and new problems.

(Approach it like an engineering challenge and keep emotion out of it, because an emotional argument cannot be won.)
