Re: "Plato's Stepchildren:" Kirk-Uhura Rape Scene?
This is a slightly unfair assumption. Many of these Trek legends began long before the internet. The only way one could research facts was to go to a library and consult something like the Readers' Guide to Periodical Literature, or other reference. I believe the "first inter-racial kiss" business actually started due to TV Guide saying how important it was during the week of the original broadcast.
What research is needed? What does it matter where it started? Folks can quash these things as they occur. Eventually, it vanishes. Like weeding a garden.
PS: I used the word "quash" without the aid of one them -- watcha call it -- "thesaurusaurus."
