Iranians are treated with respect in UAE just like every other nationality and religion. I would not say there is a lot of mixing going on in terms of social gatherings between Iranians and local Sunnis...with that said, 10+ years living here, I haven't seen a single Iranian/Shia being mistreated.
You know what is scarier than xenophobia against Muslims?
The following things:
1) Millions of babies killed each year in US, which is advocated by Liberal Party, yet strongly prohibited in Islam unless giving a birth is endangering a woman's life.
2) Agressive taxation of successful business owners, due to socialist/liberals beleive that people should be equal and that healthcare, housing, food, beer, cost of abortions for lazy people is somehow a responsibility of successful folks. Sharia does not apply work tax for poor or rich.
3) The third bathroom. In Islam, there are only two genders: male and female...and as a Muslim woman, I do not wish to share a bathroom with the man and I am not acceptive of gender fluids and 76 genders that liberal people seem to be acceptive off.
4) Women who stay with their husbands for superficial reasons such as: money & power even when a husband cheats on his wife right and left. Hillary would of made a disturbing example for future generation.
5) Woman who defend a child rapist of 12 year old girls while accusing the victim of being attracted to her rapist...THEN getting most of the criminal charges dropped against him, so he can rape another child just 3 years later...I'll be frank, I puked as I was reading the court records that I've purchased of that hearing from Arkansas court records archive for 75 USD.
6) A woman who claims to be pro-woman yet disrespects all the women her husband picks to have sex with.
7) A candidate who accepts millions in foreign donations via her "charity" while serving as a Secretary of State.
8) A candidate who lies under oath to FBI and Congress about sendi and/or receiving emails via private server. Look I don't care what's in it...I just know for a fact, if she lies under oath, she can lie any time moving forward.
9) Calling me Islamaphobic due to my support for Donald Trump. If we were in Sharia, she would of been executed shortly after and I would of watched her at it, while filming horizontally with a steady hand, using GoPRO.
10) "Deplorables" ...she called 50% of Americans as Deplorables which included Xenophobic, Islamiphobic, Sexist etc. Why does she dare to run in the country if she doesn't like at least 50,000,000 of its population? That was the point where I booked 5k ticket back to US just to vote against her. Maybe she should run in Kenya or some place else where she would actually love the locals.
Conclusion: The spread of xenophobia in US is an aweful thing, but surely pales in comparison to the damages caused to our country due to liberal ideology and a particular candidate choosen by the DNC to run for a president. Muslims believe that everything is a will of Allah...I wake up every day in the morning, I pray and then I thank Allah that she is NOT my president.
