Yes, drinking mai tai's (which are incredibly rare drinks, BTW) is like ... drinking soda pop. Way too much sugar. So are other cocktails - similar to soda pop, except consumed in quantities of 4-12 oz instead of the 12-24 oz servings of pop.
Arguing that alcohol is bad because many popular drinks have too much sugar is simply a bizarre take. It's like worrying about second-hand smoke from too much gun violence.
