I met a number of youth advocates who are working hard among their peers to get the message out there that certain behaviours, language and attitudes are not going to be tolerated.
Cefais gyfle i gwrdd â nifer o eiriolwyr ieuenctid sy'n gweithio'n galed ymysg eu cyfoedion i ledaenu'r neges na chaiff ymddygiad, iaith ac agweddau penodol eu goddef.
