Everyone knows the EFF and the ACLU are thinly camoflaged shells of their former selves, tactically pushing for whatever will advance their quest for power. Yeah, we know that if we want help defending our Constitutional rights, we go to non-psychopathic organzations like FIRE and Judical Watch and Project Veritas.
They defend strong encryption because it's a tool their side still needs, for now. Defending the Constitution and free speech is just a temporary tactic for them until they get more power, the sort of power they now wield openly on campuses across this nation and which you use to silence anyone who disagrees with them.
After that, they'll start talking about how old the Constitution is, how its from another, quainter time, and how it needs now to be put aside.... and how important it is the government oversee people's speech lest someone utter hatespeak .....and consequently we must ban strong encryption.
