I never have problems with Facebook as the only "friends" I have on there are people I know personally, or with whom I have a connection in another way. As some of these people are in Scotland, Denmark, Sweden, Belgium, Tunisia and Australia we do not see one another very often and the cost of phone calls is prohibitive, so FB is the perfect way to keep in touch. If I see posts which are racist, anti immigrant, or which condemn all moslems for the actions of the terrorists, I invariably speak out, even if I am a voice in the wilderness,
