I watched the show every day after Sesame Street and before Reading Rainbow. Good times.
I take issue with what you say here:
a> It was by no means ignoring the other-side of this
No racist ideas ever appeared on the show. That is the definition of "ignoring the [racist] side of this."
Ignoring != suppressing. Ignoring thoroughly debunked and discredited notions is healthy, and universal. NASA isn’t suppressing flat Earthers by not presenting their views alongside their scientific discoveries. It’s the job of the flat Earthers to present their own ideas, not act as social and intellectual parasites while crying that others aren’t carrying their weight for them. Mr. Rogers, on his own show, presented his own views, and that isn’t “suppressing” anything either.
Whether or not your intention is to troll, that's the effect. Please stop.
> Eschew flamebait. Don't introduce flamewar topics unless you have something genuinely new to say. Avoid unrelated controversies and generic tangents.
