You need to normalize the “abnormal.”

Parents:

You need to normalize talking to your children about the "abnormalities" of Islam.

Tell them, and more importantly, show them why Islam is the truth, and what happens to people who don't have proper guidance.

Use examples from your own life and be vulnerable with them. Show them how society is dwindling because of a lack of Islam.

You don't need to do research, just use examples from your own life experiences and from your co-workers, acquaintances, etc.

Tell them about the Hadith of the Prophet ﷺ, who said, "Islam began as something strange and it will return to being strange, so blessed are the strangers."
