I cannot disagree with what people say 🙊

I cannot disagree with what people say.

Even if I am completely right, I cannot say "I think that is wrong" or "I disagree."

I think it is because, maybe since junior high school, the habit of saying "yes" to everything and not disagreeing with people has sunk deep into me.

Since then, I have read books about how to talk well with people and how to make friends, and every book said "you must not deny what the other person says."

For example, when someone says something really strange, like "eating gummies after brushing your teeth is good for your health!"

A normal person might be able to say "no way."

But I really cannot say it. I accept it by reflex, saying "Oh! Is that so~," and I cannot have a conversation where I disagree.

But I want to fix this.

Because a little tension is important in relationships, and I think people who can properly disagree are cooler.

Fun people to be with are not people you can relax with completely, but people who have their own core and properly disagree where they should, right?

How can I say "I think your opinion is wrong" without hurting the other person?

This is my small worry right now.
