"The Link is the very foundation of our society. It provides meaning to our existence. It is a merging of form and thought, the sharing of idea and sensation."
"Because even in our isolation, we desired to learn more about the galaxy. You were one of a hundred infants sent off to gain that knowledge for us."
"You were willing to violate the most sacred law of our people."
"You will join us in the Great Link, open your thoughts, allow us to understand you. Only then will we be able to decide whether your actions were justified."
"We have never had to sit in judgement over one of our own. That's why we took so long to bring you home. There was disagreement in the link over what to do with you."
Any comparison to the Borg Collective as a single hive mind is completely ridiculous. The Great Link is a merging of the individuals of the Changeling society, and there is nothing to indicate that they operate as a single entity. Both the Solids and Changelings have consistently, in every instance, demonstrated through their actions and words that the Great Link is a collection of individuals with their own thoughts and opinions.
Indeed, every single time we've seen Changelings interact with one another, they've been in disagreement about whatever was being talked about. The "Great Link" is pretty much Changeling Internet, not single-hive-mind-Changeling-Collective.
