so bad to argue with one of them cause they have a strong idea of the opposite - however it's always a good thing to promote indipendence and freedom possibility through privacy stuff like many crypto can let us do.

Do not take to much of your time left and try to convince another friend instead - it's like nazy - you cannot talk with them.
