Cameron having an actual problem with Kathryn in early seasons is lunacy

I’m about the age now that Cameron was (28/29) when she had a genuine dislike and issue with Kathryn who was TWENTY ONE YEARS OLD getting knocked up by a man twice her age. I can’t think of a scenario where I’d have actual beef with a person without a fully developed brain that’s being preyed on by a man old enough to be her father. Sure it would be irritating to be around somebody with such erratic behavior. Cameron skated by with the whole “sweet, southern cool girl” for way too long. How does it take bEiNg a MotHeR to realize how fucked up Kathryns situation was? Being nearly 30, having an issue with a 21 year old, and standing by her old ass baby daddy is weird as fuck.
