Assalamu alaikom wa rahmat allahi wa burrahktohu,
Aauthu billahi minish shaytan nirajeem
Bismillah ar-Rahman ar-Rahim
Alhamdulillah Rabbil alameen.
I am not desiring argument with you, but it is important to fully aware people of Islam, and Alhamdulillah, Allah azza wa jal, through our debate the truth has become manifest ma'shAllah.
For the most part, you are indeed correct, talk should be not soft of speach nor private where shaytan is the third party, but, we must guard ourselves from creating rulings that forbid interaction, when the purpose of the interaction is permissable.
May allah always guide you, honour you, grant you success and pave your way to paradise dear sister. Ameen.
