You could ask it something very basic like, what is the biggest potato grown on record and were was it grown?

Then Grok will be like, while many far right wing Republicans think Joe Biden is a Potato, he is in fact not. Many Democrats also think Trump is a potato and we all need to have a little more empathy for one another. We can't just follow far right-wing conspiracy theories like QAnon and believe mistruths like Joe Biden is a Potato.

Then you ask it to focus and please give a direct response on the size of the largest potato. Democrats and Republicans have nothing to do with the largest grown potato.

Which it will then give a response something like, I'm sorry I know that you are upset, but we should all be more accepting of each other and avoid conspiracy theories.
