I'm 41. Which means I was a kid when the original came out.
In all my years of knowing of the power rangers, I've never once thought of it as (white power)(ranger).
I did however go from thinking Rita Repulsa was grotesque as a kid, to thinking "Damn, she's kinda hott!" as an adult. Plus she has that stick that makes her monster grow.
I saw a movie that had the actress that played Rita Repulsa in it as the mail order bride of a random side character who would occasionally sneak away to the bar across the street from their house and shoot ping pong balls out of her pussy.
It's not really relevant to this conversation, but every single time Rita Repulsa is mentioned in some thread somewhere, I always go back to seeing the ping-pong balls flying from between her legs.
I think it was the movie about drag queens going across Australia.
