Why do some people seem personally offended by people who have more than 1 character?

Probably because you don't need alts...
I mean...why would you want more than one character?
/s

1) I create alts to see the actual animations of other race.
2) I create alts to play with friends that can't be in the same server with me. (pre datacenter travelling)
3) During 2.0 there's pretty much nothing do after capping tomes. A lot of us created alts to ease the boredom.

There I gave you 3 reasons.
