Depends how you define 'fear'.They simply can't grasp the simple fact: no one is afraid of them.
It's not fear, but annoyance. An irritant in something meaningful a player wants to do.
Being in PP Discords and Teamspeaks, listening to (i) people making a noise like ET when he's trapped in a shed when they die to a rival PP Commander and (ii) the language used regarding shuffling off to PG or Solo when encountering opposition spoke less to annoyance, more an acknowledgement of being outclassed by a rival and the 'fear' of losing to them.
