“I have the right to say what I say” is a disingenuous and thought-terminating. What you are essentially saying is that you purely intended for this to be your soapbox, that you see your role here as dispensing your wisdom, and not to have any actual conversation other than one where people agree with you.

GP can just as easily say that they have a right to their opinion that your classification of the experience is invalid. “Yeah but I was talking about how I felt!” just doesn’t pass the smell test. Mature people can have their mind changed and can see when they were being a little over the top. Your “I felt this way, so I will always feel this way, and there’s nothing you can do to stop me” attitude is not a hill worth dying on.
