>I believe in A, I don't take a strong position on B

But if A and B are opposed, then there is a question of why a strong position on A can be allowed with a weak position on B, if the reason for the strong position on A would also indicate a strong position against B.

The underlying argument being implied (but rarely ever directly stated) is to question if your reason for the strong position on A is really the reason you state, or if that is just the reason that sounds good but not the real reason for your belief.

In effect, that you don't apply the stated reason to B despite it fitting is the counter argument to why it doesn't actually support A.

If there is an inconsistency in arguments being applied, any formal discussion falls apart and people effectively take up positions simply because they like them, contradictions irrelevant. This generally isn't a good outcome for public discourse.
