I cast "Baconstorm!"
A gamer's inability to civilly discuss (or refusal to understand!) another gamer's perspective is a flaw in the gamer, not the game.
Note the emphasized bits. I'm not knocking people who can't find common ground when talking about gaming. I'm knocking people who can't have a civil discussion when talking gaming.Not at all. That's reductionist and a bit dogmatic.
It's not a "flaw" in the game, but nor is it (necessarily) a "flaw" in the gamer.

I actually agree with you 100%. To my mind, the degree to which two gamers can talk about their respective games depends largely upon the level at which they care to talk about it, which in turn depends largely upon what their respective gaming styles are.People expect common experience. When you say you've played baseball or Pinochle or Risk, that sets up an expectation in my head. For 99.9% of games out there, that expectation is going to be almost as good as if we saw the same movie. But when you say "I play D&D" it's more like saying "I play a sport with a ball" than saying "I play basketball." But the human brain is going to treat it like "I play basketball." "I play D&D" sounds very specific and conjures specific contexts in my mind.... but it leaves a lot unsaid. My context and your context are probably vastly different.
I think gamers who appreciate PC optimization, tactics, houseruling or other "crunchy" aspects of the game will manage to find a common ground fairly easily. At this level, it's basically about the numbers, the part of the game that doesn't change much from table to table. This is akin to Monday morning watercooler talk about Sunday's football game: it's mainly a discussion about rules, the big plays, speculation about next week's games, players' performance, referees bad calls, etc.
A step beyond this are "shared" stories. A lot of people, for example, can talk about certain classic modules, at least to a degree, because so many gamers have slogged through them! In this case, a classic module is sort of like a film everyone has seen-- though their versions were different, there are familiarities.
Finally, it's almost impossible to talk to someone else about the RP side of things. At this level, the discussion turns to the story itself, the part that changes immeasurably from table to table-- even if the same module is on the table! That's the part that a gamer is "emotionally" vested in for his table, and usually utterly uninterested in for any other table. Face it, no one is interested* in hearing about my party's latest exploits and how they took out our campaign's version of Demogorgon and how the dwarf got drunk again, that crazy dwarf!
