Actually, Tanis was a product of rape.
http://en.wikipedia.org/wiki/Tanis_Half-Elven
There's a bit in the wiki article about some book down the line taking a different view, but I've read about two dozen DL novels and had never heard of that. Nor would anyone who stopped at just the original trilogy.
Yikes!

However, the fact that it shocked me indicates to me at least that I wasn't expecting a half-elf child to be a product of rape. It can happen, as humans rape other humans and a child can result, and I guess the authors were going for that to add pathos to the character (those awful humans!). But I wouldn't expect it to be the norm of human-elf pairings. Most of the elf stories I read either have the elves be so different that breeding with humans simply isn't possible, or has it be a result of desire on both sides (although sometimes adultery is involved, a variation on the "changeling" theme).
The only "loving parents" version of a human and orc producing a half-orc I have encountered was the parody in Order of the Stick, which was funny precisely because it was not the expected norm. Even Grunts, the 2nd most sympathetic account of Orcs I have read, has them portrayed as rapists. Only Orkworld, the most sympathetic account I have read, goes for the "doomed noble savage" archtype instead. And that was John Wick deliberately trying to redefine the orc.
So while I am shocked at Tanis's being a child of rape, I would still maintain that the expectation of a human-orc pairing would be rape (The orc as rapist, and the human as rape victim), and that half-orcs thus have an unsavory past that might put people off, in a way that they wouldn't be put off playing a Dragonborn (the "good guy strong guys").
A half-elf does not have to carry (and I think would not be presumed by most players, new or old, to carry) the connotations of child of rape, any more than a human child has to be a product of rape. Thus one can play a half-elf without worrying about rape in the near (or even distant) past if one doesn't want to.
The one common theme about half-elves is that they tend to be rare (why else would Tanis be called Tanis Half-elven, unless that was a rare thing to be?). Since the Unearthed Arcana for 1st ed AD&D (whereupon half-elves no longer monopolized the cleric-magic-user (or cleric-fighter-magic-user) multi-class niche), the makers of the 4 editions of D&D have thoughtfully accomodated the rarity of half-elves by making half-elves mechanically inferior to all other core racial options.
