Question

Read the sentence.

Answer 1

Not ad hominem, because that has to be directed at a person. Probably not a red herring, because that involves misdirection and clues, which seems out of order for this type of work. Poisoning the well involves making further phrases seem stupid or pointless by statements made to start. A slippery slope is an action or idea that leads to problems and issues to come, and in this case i think that applies.
