Speaking at the rally, Pádraig Mulholland from NIPSA trade union said that "enough is enough".
"Draw a line under these activities, consign them to history and let's move society on", he said.
"We should not find ourselves pushed into a place where oppression starts to happen in our society again.
"We want a fair, free, open society for everybody. We want things to change. No going back.
"There are those in society on both sides of the sectarian divide who will welcome the opportunity that this attack offers them, to stir the pot of sectarianism again, to try to take us back to where we used to be.
"But let's be clear again, there is no going back to those days."
