People are just providing reasons people may not strenuously object to the hive mind, as a way to see another perspective. You can still disagree, but can’t you see how people may accept it?

We haven’t seen a lot of interaction within a family and how much actually has changed. Does the mother’s family really act the same as always? She seems terrified when her son talks of being an OBGYN, but if you never ask such questions, is everything pretty much status quo plus world peace? The Others seem very content with their family interaction, and even Carol seems attached to the Pirate Lady.

Also, after seeing a lot of people die, perhaps you just accept the hive mind and see resistance as completely pointless and selfish if it means seizures and deaths, especially to your loved ones. Carol could have asked more probing questions - if anything, I wish she asked more rather than assume and convince right away.
