Are you saying that you think banning perfectly normal everyday things "because terrorism" is ok,

... or did you miss the invisible sarcasm tag?

Terrorists do use the air to convey voice; air is their primary communication medium for propagating their terrible ideas, and arranging their despicable plans. If we denied them access to air, to stop their voice communication, it would severely limit their ability to harm us. Isn't saving even just one child's life worth it? And don't worry about the terrorists without air not being able to talk about the legal, daily matters. Relevant institutions are already equipped to handle deaf and mute people. They could also just use internet or other service.

Just deny them air so they can't talk, okay? It's the common sense solution. /s

Slippery slope is a thing, especially when actors with under-handed intentions ask for simplistic, ham-fisted solutions. Once a precedent is established for censorship or snooping, it's pretty hard to draw, and defend, a line in the sand.

No.

Yep, but we shouldn't do it by throwing away the freedom we try to defend
