In a shift in attitude, most young people now say it's wrong to use racist or sexist slurs online, even if you're just kidding. But when they see them, they don't take much personal offense.

A majority of teens and young adults who use the Internet say they at least sometimes see derogatory words and images targeting various groups. They often dismiss that stuff as just joking around, not meant to be hurtful, according to a new poll from The Associated Press-NORC Center for Public Affairs Research and MTV.

Americans ages 14 to 24 say people who are overweight are the most frequent target, followed by gay people. Next in line for online abuse: blacks and women.

"I see things like that all the time," says Vito Calli, 15, of Reading, Pa. "It doesn't really bother me unless they're meaning it to offend me personally."

Even then he tries to brush it off.
