Could you help make my opinion better?

Question: Do you think Japan should make English as the official language?

My answer: I disagree. Even though English is widely spoken in the world and it's convenient if we can speak it, the adoption may cause great confusion. In addition, if we stop using Japanese, it will disappear, which we should avoid and we must cherish our language

"I don't think so. Even though English is widely spoken throughout the world and it would be convenient if we could speak it, it's adoption in Japan might cause great confusion. In addition, if we stop using Japanese, it will disappear, which we should avoid. We must cherish our language."

You shouldn't say, "I disagree," because there is nothing to agree with. If the question was, "Do you agree that Japan should..." or, "Someone said Japan should...", THEN you could write "I disagree." But, the question was "Do you think..." so your answer should be something like, "Yes, I think Japan should..." or "No, I don't think Japan should..."
