So, it is best to leave them when they involve in such things. This way, at least they will find out why you don't want to be part of their gossips. And hope Allah guides them and helps them to get away from these major sins.
As far as the people you think you have backbitten, talk good about them in their absence and make dua for them. There are good and bad people in every race. So we should not generalize and assume all people from a particular country or race are bad. May Allah make it easy for you to practice Islam. Ameen!
