Despite that the original St. Patrick’s Day was an effort to celebrate Irish culture, daily discrimination still wore on Irish communities. Moreover, Anglo American society pushed the Irish to assimilate into mainstream culture—in other words, to become more American than Irish. This assimilation occurred twofold: not only did Irish Americans suppress their own heritage, but many sought to turn the discrimination they faced against others, such as toward Black Americans and other immigrant groups. To escape oppression, they would oppress others
Assimilation as a cycle: changing our own ways of doing in order to fit in doesn't just help us to "escape oppression" because part of fitting in means adopting ways of doing that include acting out oppression.
