I don't think this statement has the effect you want it to have. You're not laying out the experience you're speaking from. You're just setting it up so that no matter how reasonable the next thing you say is, it will appear maximally arrogant and condescending.
I disagree. It's fine to contextualise that an opinion solidifies over time.
And your parent is right to point out that emotionally loading posts tend to be a disservice to the message being carried.
