Are people like this really alive O.O?

Ok so i was watching a show on tlc, i think it was called the worlds smallest mother or somthing. And basically it was about a little person, like really little, who had a baby, and it could of killed her cuz of her size and such, but, she was reading e mails where people were saying stuff like..."All Midgets need to be killed at birth or before they are bourn, to ensure they dont taint he gene pool"(i think the people who say stuff like that are the ones we could really do with out-.-) And "All midgets need to be killed at once, that will solve the problem" (People....Avarage sized people give birth to little people all the time...check ur facts) And i just dont get it, one of my good friends is a little person and shes totally...well not normal lol, shes rather unique...but you know what i mean, i dont view her anydifferently then my other friends......just...do people really think that stuff ^
