Personally, it was initially because of Lolorito and Teledji...and much later Yuyuhase. I literally wanted to strangle those little muppets. Plus, as an Elezen at the time, I was always worried that if I offended Lalas, they would try to bite my kneecaps (old joke from FFXI). Even having several friends who played as Lalafell was not enough to convince me otherwise.
Then I met Cocobusi and his brothers, Pipin, Wedge, Tataru, the mining twins (I forget their names now) and of course Nanamo and they greatly realigned my dislike towards that race.
So yeah...I'm fine with what they are; and as for the people who play them, it boils down to the person's innate character not the Lala race itself.
