I think that many debates of ideas are lost when one party responds in a joking and ironic way, treating the other like a complete idiot. I know it's difficult to stay balanced with someone who thinks radically oppositely, but a reflection is in order at this moment:
-- What made the person think that way? Family life, circle of friends or educational influence.
I believe it is possible to convince someone, but it will depend a lot on the approach.
Before finishing, silence is an excellent conflict mediator. Congratulations on the post👏🏻👏🏻👏🏻👏🏻
