If we are doing imaginary situations, the proponents of this bill can also do something like this:
Imagine there is a bar, where the police are unable to go inside. Every day, people go into the bar to plan terror attacks or to spread hate and racism. They can have whoever from across the world join them in the private bar without the police being able to find out. Sometimes they also bring young children into the bar to sexually exploit them. Other times, they bring vulnerable young men and indoctrinate them with their racist hate. The owner of the bar knows that those kinds of things are happening, but they say, a lot of people just come into the bar to talk with friends, so we never allow the police to come. In addition, before serving drinks, the owner puts on a blindfold and stuffs their ears with cotton so they won't be able to see or hear what is going on. They live by the principle: See no evil, hear no evil. The owner of the bar is making a lot of money from the people using the bar.
Don't you think we should keep the terrorists, and neo-Nazis, and child molesters from having a bar that they can go to to do and plan their evil stuff that police cannot get to? Don't you think that the bar owners, instead of stuffing their ears and covering their eyes so they are unable to see the bad stuff, should make sure that bad people aren't using their bar for evil stuff. Sure, just like in the real world, you will have your privacy just like you have in your home or at the local bar. But, you would want a real life bar owner to not close their eyes to people using their bar as a planning ground for terrorism, or who are bringing young kids with fake id's to the bar to exploit them, or who are filling young men's minds with hateful, racist lies? Also, just like the police can get a search warrant for a bad person's home or a bar where a lot of bad people are congregating and planning and doing bad things, we think they should also be allowed to do that in the online world.
Now tell me, to the average non-tech voter, which will pull the most emotional strings?
