Woke potato is a person whose mental capacities have been destroyed by ideology. It refers to the slang use of potato as someone being uninteresting, dull or strange. Many social science disciplines produce woke potatoes, for example Feminist studies which cherry pick all evidence which shows women to be marginalized while ignoring all the evidence - especially legal regulations - which show women to be favored.
A characterizing trait of woke potatoes is that they cherry pick their evidence so that it suits their ideology. The worldview of a woke potato is unscientific, subjective but always politically correct.
John: What's Chris up to? I've heard he is studying women studies at University of California?
Michael: Yes, he really changed and he is now this bitter, rambling sob. It's hard to talk to him now.
John: What do you mean?
Michael: Well he lives in this strange echo chamber. He basically ignores all evidence that does not support his worldview and is always rambling about the patriarchy.
John: Sound like he has become a complete woke potato.
Michael: Very true. It's difficult to reach him since he does not accept empirical evidence. It's all about historical injustices and narratives, and of course a lot of cherry picked evidence.
