People from some cultures (typically those where Islam is dominant, but not exclusively) are more prone to behavior like this. Probably due to a system of values they have adopted in their environment and upbringing.
Call it Islamophobia or something else it does lend itself to the idea that some people should be regarded with more default suspicion than others, based on their origins. As long as each individual is treated as just that - individual, and not blamed for the crimes of others, a higher base level of suspicion is unfortunate but a normal human reaction that shouldn’t be treated as some kind of horrible sin.
Change imposed by force never works. Iranian people need to overwhelmingly decide to do it. Providing help is fine, but bombing them into “freedom” never works. It actually has the opposite effect, when you feel in danger (because for example bombs are falling around you) you’ll less likely to start a revolution.
