No protestants believe Unionism benefitted from GFA?

PA writer Ed Carty gets into the ESRC report that Pete blogged below. He fastens on to the figures that indicate Protestants still feel they did badly out of the Belfast Agreement:

Almost seven years since the accord was ratified by referendum, the study finds 85 per cent of Protestants feel nationalists got the best of the deal. But the report from the Economic and Social Research Institute shows most Catholics think unionists and nationalists were treated equally. The research also shows no Protestants believe the accord benefited unionists – a drop from 5 per cent in 1998.
