Unfortunately, yes, these incidents occur. There has been a sharp increase in the past year, not just against Muslims.
Some scholars believe that the violent backlash against Muslims is driven not only by the string of terrorist attacks in Europe, flood of refugees to Europe, but also by the political vitriol from Donald Trump and far-right politicians/candidates who have repeatedly used Anti-Muslim rhetoric, and are trying to ban immigration from Muslim countries, and enact laws discriminating against Muslims.
Very troubling and relevant, I read in the news yesterday, that the European Court of Justice (the EU's top court) ruled that employers are allowed to ban workers from the "visible wearing of any political, philosophical or religious sign" including headscarves.
I don't know about Europe, but at least here in America, most people are against this type of hate crime, which has been increasing not just against Muslims, but also against Hispanic and Latino people, against the LGBTQ, against African Americans, against women, and even against Asian Americans like myself. The majority of Americans are against these hate crimes, and speak out either in protests and demonstrations, on social media, by calling their politicians, or even by making little games or art.
Unfortunately, there are too many people who do nothing about it, and there are still too many bystanders who do not want to get involved when the hate crime is happening. In some parts of America, the population is not very diverse, and has little exposure to non-Christians or non-Caucasians, other than what they see on TV, and they watch right-wing biased news channels which spread anti-muslim anti-immigrant fear to keep and increase their viewership. It's really a war of media and memes - do we choose fear or do we choose empathy?
How is it in Iran recently? I understand that women are forced to wear the hijab in public or will be punished or fined. Ironically, before 1979, women were banned from wearing the hijab, like some places in Europe currently. What is the opinion among demographic groups in Iran about the forced hijab? What do you think about the future of hijab restrictions as a young Iranian? (Are you allowed to speak about it without getting into trouble?)
