I used to be afraid of publishing things because I was afraid I might be wrong.
“What happened?” you might ask. “Did you suddenly realize you were right?”
No. I am still often wrong. Some things I write are stupid. Some are embarrassing. But I still write to them.
Because you, as a writer, have the right to be wrong.
This doesn’t mean you should consciously deceive people. All this means is that you have the full freedom of saying whatever you want without being too afraid of what “they” will think.
Reverse that and you’ll get that we, your readers, reserve the right to disagree with you. We can voice our opinions. Or write something ourselves that will counter what you wrote.
And that’s OK.
Be wrong. Disagree. This is not a test.
