In Desperate Housewives, does the storyline between Katherine and Robin exemplify "lesbian entrapment" or the evolution of healthy individuals in a complex relationship?

The storyline between Katherine and Robin depicts the formation of a same-sex relationship between a historically straight character and a lesbian.

I’m using politically charged terminology to discuss the storyline, to debate the possibility of DH writers having a hidden agenda, and to delineate the nature of same-sex relationships in general.

Terminology defined: the idea “lesbian entrapment” stems from the belief in the “gay agenda.” More specifically, “lesbian entrapment” is a phrase used to identify the role of two women: one is a perpetrator, the other a victim. The perpetrator uses emotional and psychological manipulation in order to seduce the victim, who may have always been identified (by self and/or by the other) as straight or bi-curious. The “victim,” under normal circumstances, would have never pursued a same-sex relationship.

Note: Both the expressions “gay agenda” and “lesbian entrapment” are politically charged and potentially offensive. Personally, I am neither supporting nor speaking against either or both expressions. I am simply using them as terminology to discuss the question.
