Why would you think about wee wees when looking at a pikachu next to a trans rights flag?
As for answering your question. Maybe not polar opposite. But nationalism is pretty common on kids shows, I cannot think on many things as political as nationalism. Certainly “I support this particular nation” is a far more political statement that “I do exist”.
No, it does not.
Let me get this straight. You see a picture of Misty. Do you think of her genitals?
If they tell you in the show that she is trans, do you start thinking about her genitals?
That’s weird.
