Religiously watching more than a handful (I'll be generous) of reality shows. I get it if you have a guilty pleasure or three. But if that's all you watch, chances are you're breeding trailer trash half wits who see nothing wrong with rating candy bars for every meal of the day.
Now I personally fall below your threshold, but I've always differentiated between celebrity reality TV, like keeping up with the Kardashians, Real Housewives of Beverly Hills, from Competitive Reality TV like Survivor, the Amazing Race, from whatever you'd call reality TV based on odd professions or personalities like Deadliest Catch, Duck Dynasty, etc. If there is a reality TV show associated with a persons hobbies (like duck hunting, or driving on "ice roads") I'll give 'em a freebie on watching reality shows associated with that. But I have pretty much zero tolerance for the trashiest of the bunch, like Jersey Shore, Real Housewives.
The thing about all of them is that even though they're called "reality" TV, the producers are actively making things happen so that the crew being paid to film and edit it all can do so without having to weed through 1000s of hours of nothing. Even the competition shows are manipulated by production. Pawn Stars has been shown to be at least largely staged. This stuff is not reality TV, it's semi-scripted, production driven, shows featuring amateur actors.
So I differentiate because I watch Survivor, Amazing Race (probably best of the bunch) and Big Brother (worst of the bunch). It's easy to look down on them, but I like watching how people act in a social game motivated by an easy payday.
