Really? All of those are dealbreakers for you? Some of them I can kind of understand, like players who hog the spotlight or DMs who favour their partner over others, but I feel like some of these are a little excessive as dealbreakers. But whatever floats your boat, I guess (or, considering the thread topic, whatever sinks your boat).
Yes, really. I have walked out on a Spelljammer campaign. I have walked out on a campaign in which characters were modeled on super-heroes (specifically, Wolverine, Green Lantern, Doctor Strange, and Iron Man). I have turned down offers to play in Eberron and Planescape.
Things like he Dm having thought about their setting and having house rules ready prior to character generation are important for me to decide if I have an interest in what the DM is offering. The campaign information is also important to help ground me in the setting and therefore my character.
With regards to specific campaign settings and styles, I have a strong dislike for many elements in Eberron, Planescape, and Spelljammer. I am also easily bored by both hack n' slash, dungeon crawls, and Monty Haul style games as well as campaigns built around puns, camp, parody. There is no point in my wasting my time with those settings or styles. Finally, for Evil campaigns, I don't see the point. I am there to play a heroic character fighting evil.
In terms of races, my preference is for all human campaigns. Barring that, I am fine with the traditional races of 1e and 2e along or perhaps one or two of the following as PC races: half-ogres, orcs, kobolds, gnolls, lizardman, and minotaurs as PCs (just no more than one or two in the party) . In an Asian themed settng, I am fine with some other races. However, many of the PC races introduced starting with 2e are not the type of fantasy in which I am in interested or I find the concepts to be extremely lame (and often a desperate attempt to create something interesting and hope it "gains traction")-again, not the fantasy that interests me, personally. Therefore, why waste my time playing in such a game. Others mileage may vary and all that stuff.
Some of the things make me wonder why we are not playing with a different system or wish we were. For instance, if the characters are based on super-heroes, I am going to be wondering why we are not just using a system like Icons: Assembled, Marvel Heroic, Supers! Revised, Mutants and Masterminds, etc. Similarly, if we are blending fantasy and technology, I would much rather use one of several other systems other than D&D (Savage Worlds, Cartoon Action Hour) . I don't like the AC system, Levels, Hit Dice, etc when technology is introduced. Furthermore, there better be a strong theme for the blending of fantasy and technology (e.g., a Thundarr the Barbarian type apocalypse).
