No one here knows that you are just 22. A sensitive heart always accompanies a bright mind.
Life has just begun for you, dear son! You are fortunate to know the Truth at 22. Most people don't know or learn till they reach their graves.
How to convey the Message? For example, keep Hadith Bukhari ready online or the book. Then read and highlight the Chapter on NIKAH (Marriage) and the Chapter on GHUSL (BATH). Ask them like a student: "How is this possible?" Do not argue. Some of them will change right away, others will take a few weeks.
May Allah bless you!
