Ineed with 4 main ideas to discuss on my research essay about why americans are clueless about new immigrants

1. Liberal propaganda.
2. Most of the TV channels reporting fake and selected news.
3. Most of the integrated Muslims (that have living tradition for few decades in USA) the Americans have been in contact with in the USA are taken as an example, and that is way to far from the real picture.
4. Not enough knowledge about the Islam and how things work in most of the Islamic countries, from where most of the immigrants are coming.

Answer:   [b]:   "cultural" .
