Anything they see in there that goes against their own personally DESIRED to be status quo is an insult. Theyve just got shit views so well rounded culture shocks them and it reminds them all about how their shit stinks and they aren’t really all that smart or morally sound. Cause if they were, they wouldn’t have identified with any that stuff to begin with or realized the perils.
And it makes them know the cringe at how they’re viewed (but they say its just how they’re PORTRAYED to pass the buck on being that way being their own fault and indicative of their lack of stats and general lack of character)
