I see your point but I think those things can be chalked up to Fi Hidden Agenda (or Suggestive) rather than Fe Suggestive. IxTJs (like IxTPs) have very weak Fe but they're much less receptive to it. It's their PoLR function so it's very painful for them. Like how Sheldon just left because he didn't want to deal with the sentimental goodbyes, when he was gonna move to another city. Or how he doesn't want Leonard to make jokes. Or how he's constantly insulting everybody. Fi PoLR types (ExTPs) can do this too, but, if I understand correctly, they do it for 'fun', to 'lighten the mood', etc. Sheldon doesn't do it for fun. Fe PoLR (IxTJs) is the last type you'd think of as 'fun'.
