No. No one is going to react that way because of your race. Not in TESO, Not in Warcraft, not anywhere. Stop over-exaggerating, and stop over sensationalizing the argument.
"race/class" combo has nothing to do with having a +5% Mount speed talent in a boss fight, when you're passing up a +5% damage talent.
Trolls in Throne of Thunder had an advantage, but only the top 10 guilds, +/- 2, cared enough for the racials. And at that point, if you're in those guilds, you're "elitist" enough that something like this doesn't bother them.
