Could it be that they execute honosexuals and treat women like second class citizens?

Nah, it must be racism.

No. It's neither about race nor ethnicity; it's about culture and religion. It's not about the people, either, since the differences from person to person are as pronounced there as everywhere. It is, though, about the society built with the culture in question as a foundation. You can criticize societies everywhere, starting from your own - it's normal, healthy, and has nothing to do with racism.
