In skits, songs, and other performances they epitomized the social skills fundamental to Sesame Street's mission--cooperation, understanding, tolerance and respect...a "social agenda" alright, but -

Ditto Mr. Rogers, an adult who appears to fully comprehend the sorts of things which frighten young children - as they watch the adults around them shouting and carrying on over mysterious Words..
But I guess this is just another case wherein a merely descriptive word has come to join the cacophony indicated by, say
Right to 'Life'
A Woman's Ownership of Her Body
and all the other 'issues' in the automatic war of opposites. (I do wonder though - what 'opposite' to the above agenda is in some minds.. as find these ideas also subversive ??)
