You think slippery-slope arguments are always invalid on their face, but you habitually resort to argument ad hominem (i.e., “the fallacy of believing you have refuted someone’s argument merely by pointing out certain features of the arguer, not by showing that anything is wrong with the argument itself”), often compounding it with as many examples of the straw man fallacy (“a fight in which one of the combatants sets up a man of straw, attacks it, then proclaims victory … while the real opponent stands by untouched”) as your imagination can devise.
