Cal, you scare me sometimes, because I could have written your post exactly.
Seeing as you already posted it for me, I’ll volunteer that there is only one kind of mayonnaise: Hellman’s. (“Best Food’s” west of the Rockies!)
(Homemade is also acceptable.)
Science fiction/fantasy (written) - if the writer didn’t invent the world in which the story is set, I’m not interested. That means no books in worlds from originating from movies, TV series or RPGs settings*, no sequels after the author dies, and no fanfic. Short stories by established writers in “tribute” anthologies are borderline acceptable.
- If the writer was involved in creating the setting, I’ll accept it, but I retain the right to ignore its existance.
Anti-purist- Christmas trees: the fake ones are the best. They are perfectly proportioned, nicely shaped, don’t shed all over the house, and are photogenic. I think they look great in my holiday photos.
Purist - Tea: I don’t know definitively where tea originated from, but I’m going to guess China. In most east Asian cultures, tea is traditionally taken plain. No sugar, no fruity flavors, none of that nonsense. I can’t stand the added sweetness. Just leaves and water, please!
Potato chips. No BBQ, no vinegar, no ranch cool or otherwise. They should taste like potatoes and salt.
Purist: Levi’s 501 are the only jeans allowed. Dunno why but just the way it is
Anti-purist: Jorts are not acceptable wear for a male. Cut off 501’s are fine but taking a pair of jeans, hemming them and then pretending this is some kind of acceptable fashion ranks up there with a bald comb over.
Anti-Purist: Single Malt Whisky snobs that ask for 1 single ice cube. If you want to get the chemical interplay, then a little bit of water works. If you want to blasphemy and ice your whskey, then pour it on the rocks already.
Purist: Mac and cheese cannot come from a box. The cheese must be real, must be fresh.
Anti-purist: Beer. While I don’t consider Miller, Budweiser, and Coors to be beer, I’m fine with mass market beers like Yeungling, Samuel Adams, Stella Artois and a few others.
Purist: Cheese - Kraft slices are not cheese. Even the package calls them cheese food. Go to the deli and have them slice you some mild cheddar.
Purist:
Computer, monitor, keyboard: Apple.
Camera: Nikon (D90) with Nikon lenses and accessories.
Peanut butter: peanuts and salt, period.
Spread: Real butter, salted.
Crosswords: NYTimes, preferably Sunday.
Cookware: Calphalon.
Wall paint: Behr.
Batteries: Durocell (Energizers don’t work in my stationary bicycle).
Painting supplies: Lascaux Studio Acrylics, Windsor & Newton 994 series brushes, Fredrix “Alabama” canvas, and Pearl Paint heavy-duty stretchers.
Shoes: New Balance, Skechers or Timberland.
Purist: Coke with NO ICE. I’m sort of like the whiskey guys upthread, except with soda. It has to be Coca-Cola, preferably from a bottle. It can be consumed from the bottle or poured, but it must be cold and not over ice. Ice melts and dilutes it! And every restaurant in existence seems to think I want a glass of ice with some soda added to it!
Purist: NY Times crosswords AND Suduko, and only Will Shortz. None of that Eugene Maleska crap. Crosswords are to be done in ink with a Pilot extra-fine rolling ball pen. A Bic .7 mm mechanical pencil is used for Suduko. Each are torn neatly from the book or newspaper and done on a clipboard.
Purist: Stickshift. Dear god, only a true stickshift.
Purist: Anyone who fries eggs in something other than butter is a monster, a monster I tell you!
Purist: Though I had a “what have I become?!” moment after I banned any Dungeons & Dragons edition past 3rd from my gaming table, only a few short years after mocking my old DM for staunchly sticking with his 2nd edition, I’m still not touching 4th. It’s just not D&D.
The Designated Hitter rule. An Abomination. Pitchers should be made to hit.
I prefer my zombies slow.
Purist: Beverages - Pepsi, not Coke. Diet Dr. Pepper, no other diet drink. Earl Gray tea, not black or orange pekoe.
Condiments - Heinz ketchup. Grey Poupon mustard.
Computers - Apple.
I’m not a purist about anything else of note.
:eek:
Breyer’s did WHAT? I don’t get ice cream often, but I always bought Breyers when I did because they were pretty much true ice cream. I guess it’s back to reading labels…
Suranyi, mah brothah!
I was about to post that I am a purist of Nothing, then I saw this post.
Yeah, it’s gotta be the NYT crossword (even better, the Sunday NYT). Any other I won’t even look at.
mmm
Watching movies at home:
PURIST: Must not be edited or altered from the director’s version (unless approved or done by the director). Aspect ratio should be original (no Pan and Scan or cropping). When applicable, subtitles, not dubbing!
NON-PURIST: The above when it comes to anime. All anime is dubbed so it’s hard to be a purist on that account. Plus it’s just cartoons anyway. 
nitpick: sudoku
If Earl Gray is your favorite tea, that’s fine, but your sentiment above doesn’t make much sense. Earl Gray is black tea, black tea that has been flavored with oil of bergamot. At least, traditionally it is. If one is going to be an Earl Gray purist, I think one would have to insist that any tea going by that name be black tea, and not some other type of tea flavored with bergamot.
Purist: my beer must not contain any corn or rice.
