the bacon and eggs/Cathy cartoon
that's not a cartoon, that's a REAL picture of a REAL video. It's a visual aid to help understand how illogical you are arguing. Perhaps you should watch the video to see what NOT to do, instead of calling it a cartoon.
should it be allowed to yell "fire" in a crowded theater
please enlighten me, how would a ban on speech stop anyone from doing that? It wouldn't magically make the words disappear. Every time stupid people act out, you can't just make another ban. Your ban ends up limiting the rights of law-abiding people simply so you have a tool to punish people that are idiots.
Attempting to ban bomb-making information is like trying to catch sand through a sieve. The Internet has opened the floodgates of knowledge no one can close. Even if attempted self-censorship by Internet search engines and social media websites successfully kept the flood of information at bay, other websites would continue to publish and there would always be the print versions of these instructions.
You see how that works? Turns out terrorists are smarter than you, and won't adhere to your bans, criminals always find a workaround, so it makes no sense to push the rights of civil people into dystopia for the bad apples.
