There is a specific Halacha not to do business with Avodah Zarah, you are not allowed Benefit from it, Even if you think its stupid and would never do it yourself
, One could discuss chilul Hashem or other things with Toeivah, but its not the same Halacha. There is no Halacha that you cant finnancially benefit from such and event. Only that you dont do the Averirah.
