"Ich, will it ever get better where people will stop goading others of a different culture or is it too well embedded in their tradition that it will never ever end?"
Probably not, if you put it like that. Wherever you get rival factions you will always get goading and provocation. Just look at football matches and political marches all over the place. Arguably if you let people express themselves freely so that they don't feel that their tradition is being threatened or dominated by the other side then you will reduce the tension. The ending or virtual ending, of terrorism, has also helped do that.
Unfortunately the reality on the ground in Belfast in particular means there are lots of communities living at close quarters with "the other side" and all sorts of fears and misunderstandings mount in those situations. And sadly there are still people about on both sides who are only too happy to exploit those things.
