I guess this is nothing to do with American v British English, but I do find it irritating that many people nowadays, when accused of wrongdoing or malfeasance of some sort, will say, "I refute that." When I hear that I expect the accused to follow up with a sentence containing evidence to disprove, contest, rebut, or otherwise counter the allegation, but I seldom hear anything of the sort. In reality, all the accused has done is deny the allegation, not refute it, so why not say, "I deny that/it." I wonder when it was that refute changed its meaning of offering a disproval, or similar, to it now meaning a denial? Slainte.
