"making apologies for", or to be "an apologist", in this context is someone who defends a controversial idea. https://www.dictionary.com/browse/apologist
My read sees an implied "apologies are not enough."
not sure, but maybe they mean apologetic in the sense of being an apologist?
do you mean "and something to be apologetic about"? the two clauses in this line seem to be contradictory the way I'm reading it.
