I disagree. If Islam were to be banned, it would be an attack on freedom of speech. This also wouldn't even work well. Even if it were banned from being practiced, it would be practiced anyway in the privacy of their homes. Every Muslim's beliefs wouldn't change. This wouldn't achieve anything. People would still be afraid of extremest.
Peaceful Muslims believe in freedom of speech. I guess you're referring to the extremists, who don't. They should be kept far away from anywhere that's civilized, I agree with that for the most part. But none of what you've said has supported the idea that Islam itself should be banned from public practice. You seem to keep hanging on to this idea, no matter how many times you get debunked. I think it's time to give up bud.
