i think it could be just a translation thing tainted heart, now i know you are American, another example is the word "nasty" in your country there is probally not much worse a word to describe someone, if you describe someone in American english as "nasty" that is meant to be a major insult, whereas in England it would just mean there not very nice(not nearly as harsh) and not really a mojor insult, we tend to turn to swear words to actually insult someone. hope you don't let it get to you, and that you get it confirmed that it wasn't meant as an insult.
