Like most people I have little time for them, but nor do I like other groups, like religious nutters who ring the doorbell when I'm having Sunday lunch and the louts who make town centres unsafe or even no go areas at night on weekends....there are many groups that we would be "better off" without, but that's just life. The Swiss had a fix for Gypsies - for many decades until 1972 they hunted down the children and removed them permanently, placing them into institutions of one sort or another - it didn't seem to work....
Nb. History may well despise those many millions of us who for generations were and are slaves to the "factory buzzer" going into vast sheds without protest from dawn to dusk and in winter never seeing daylight until the weekend - like something from HG Wells....
I think it's a safe bet that history will treat gypsies more favourably.
