Irish person here. It should be noted that the Irish have a completely different perspective on Cromwell. He is usually regarded here as a genocidal maniac because he wiped out between 15% - 80% of the Irish population [1], depending on the historian you believe. Not a nice man in any case, or someone to be admired.
