The popular picture is they create problems. Most of it is untrue. What they do of course is to beg and extort money. At traffic lights or during weddings or after births. They are amazingly organized and rarely will more than one group of eunuchs come asking for money.
All eunuchs belong to a small group called a toli, consisting of a guru and a chela.
Each small group is accountable to a bigger group and so on. Each group is assigned a territory and turf battles are rare. Eunuchs in the Western world are probably not as organized at the micro-level, though at a macro level they are probably more powerful. Maybe it is time Indian eunuchs got onto the net. Eunuchs though have started re-inventing themselves.
