I think it's totally fair for them to glorify their founding fathers. Every modern state glorifies it's founders in such a way, and it reflects on the principles of the country as well. Modern China idolizes Mao, modern Russia idolizes Lenin/Stalin, modern Korea idolizes Kim Il Sung, India with Gandhi, the Philippines with Jose Rizal. Naturally the US glorifies a handful of elitist genocidal slavers, and I think it reflects on the country it's always been.
