I wonder if anyone has thought of this, but Ranma can still be acting

DOES match his actual situation, but is opposite in polarity. Imagine
the same speech but the male elements female and vise versa. You come
out with something that remindes me about his speech to Kasumi in the
start of this story. I feel his running and crying afterward is because
his carefully contrived speech hits too close to home.

I think you are perfectly right here.  I cant say it more accuratetly.

Salut bien !
