An unanswered question is not the same thing as an unresolvable objection.
That is, the ability to raise a difficult question does not, in and of itself, discount a theory, idea, or proposal.
Every suggestion invokes its own unique set of challenges and concerns.
How do we implement that? Where do we get the resources? How will we ever find the time? What if others don’t cooperate? How do we get from here to there?
There is literally no proposition that is exempt from the possibility of inquiry, investigation, or interrogation.
When questions arise, it is of the utmost importance that we treat them for what they are: questions—questions that can potentially be answered with a little work, a little research, a little contemplation, a little patience, a little something more than refusing to entertain an idea simply because all of its tough questions can’t be answered in a short amount of time.
