This is a false equivalence
From ChatGPT
Saying that sugar is “worse than alcohol” compares only their possible long-term health effects and ignores the harm caused to other people.
Excessive sugar consumption mainly harms the health of the person consuming it. It can contribute to obesity, diabetes and other illnesses, but eating too much sugar does not intoxicate someone, impair their judgement or make them unsafe to drive.
Alcohol can harm the drinker, but its effects regularly extend to innocent people through drunk-driving crashes, domestic violence, assault, neglect and alcohol-related behaviour. A person can choose not to consume alcohol and still be injured or killed because somebody else did.
So even if both can be unhealthy when consumed excessively, their wider social consequences are not comparable. Sugar does not cause intoxication; alcohol does.
