'If we teach sex education, students will have more sex; then unplanned pregnancies and diseases; then they drop out and never succeed in life.' This indicates which fallacy?

The reasoning drags attention to remote, alarming outcomes far from the real issue.

The question at stake is only whether sex education should be taught.

Instead the argument piles on more sex, disease, dropping out and lifelong failure.

Each step grows more distant and unproven, pulling focus away from the actual point.

Diverting the discussion onto such an irrelevant trail is a red herring.
