This is a problem in a number of cultures, men interrupting women and other men when they speak. Not only is this rude behavior, it takes away from your message. People are less likely to listen to you if you come across as a rude boorish individual. Don't do this to others, especially sisters. Don't assume all Muslim sisters are the same Just because your mom, who was born and brought up in a Muslim country, and has never had a problem with hijab does not mean that other Muslim sisters have the same experience.
Muslim sisters are as different as brothers, as are their experiences with issues like hijab.
Many Muslims sisters know more, and they prefer more interactive lectures as opposed to the passive style normally used. If you're giving a talk, be ready to have interjections from Muslim sisters. Welcome these, don't shun them. Choose your words very carefully If you're doing a presentation on women's issues in Islam or responding to a basic question, make sure to choose your words extremely carefully. Know the exact dictionary meaning, as well as the meaning in everyday usage.
