They are not forced to abide with!they are free to abide to what ever they trust and believe! however they have to put 1st abt nationality.in fact it's not harassmen if they say so.they feel to be harassed bcoz the govt in some of their aspects/agenda's is against!,not to them,but to their act and agendas especial those which seems to pull back the country from stepping to improvent and development.take a look forexample abt mwal nyerere hydro power project, what they have been saying !!should the govt listen to whatever they argue!? My opinion the opposition part have to accept to move to the equilibrium,not always to be to one pole.
