top tips, big himbo energy, be earnest and friendly. dont try this with a topic thats actually important to you. but do pretend its important to you. you're totes energised about this whateveritisthing.
you'll know by the second reply from them that they're a walrus, itll be short, wanting more details and proof in a way thats too obtuse based on your original offering.
stay cheerful, leave all logic and deep thought behind immediately, this is going to take a few responses to perform the turning manuevre correctly, but you want to just start pivoting the reasoning and direction of your answers so instead of a straight line where youd be making a solid point, you're performing more a curve that they have to squint at a little.
get to the point that you've curved your answers enough that you're now in your confusion, inadvertently supporting the opposite of what your original point was. This is your hook. The walrus thinks they have no stakes, but the reason they started this attack is because they disagree with you and when shown an opening to win an argument they were pretending not to be having, and they will bite.
But the juice is in your earnestness, because to you they werent arguing against you, they were just asking questions, so now you can be confused at the poitn they're triyng to make and by now they have bought that you are an absolute patsy, but their only way to get out with their satisfaction with their win is for you to actually understand, but sadly you're confused and need them to explain..
