Speak up politely when you hear stereotypes, check on the person and listen. Learn from sources written by Muslims and ask questions with respect. A simple act of support can mean a lot to someone who is targeted.
The fuller answer
Many Muslims face suspicion, insults and discrimination in some countries, and women who wear a headscarf are often the targets. If you see harassment, stand with the person, do not argue with the abuser but help the person to leave and, if needed, report it. Avoid treating any Muslim as a spokesperson for all Muslims.
The Quran tells Muslims to be just even to those who dislike them, and Islam teaches the value of those who stand for justice. Sharing a meal, visiting a mosque open day and getting to know your Muslim neighbours are among the best remedies for fear.
O you who have believed, be persistently standing firm for Allah, witnesses in justice, and do not let the hatred of a people prevent you from being just. Be just; that is nearer to righteousness. And fear Allah; indeed, Allah is Acquainted with what you do.
O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted.
