To me, the biggest Treif of this year’s Olympics, is:-
1) Having the opening ceremony on a Friday nite, especially with Israeli athletes participating in this ceremony being Mechalel Shabbos b’Farhesya.
2) Having the opening ceremony on Tisha b’Ov nite, a nite which has and still does portend disaster & sadness.
3) Albeit I’m not a Muslim, but having the Olympics during the month of Ramadan, and religious Muslims fast, shows total lack of any respect and tact for any religion or religious values.
As for all the other issues, that is the IOC’s problems, and the absolute least of my concerns.
