AIBU to be annoyed when I make a really good point on a thread

[SerenityNowAKABleh]

and then it's ignored, and either I have to repeat it, or then someone else comes and makes exactly the same point and everyone goes "oh yes, that's quite clever" "what a good and inciteful point" and so on. Maybe I should just type in caps?
So, AIBU?

We can't possibly marry Gibbon off without her presence!

I say pah! to your Archduke, I 'ave my Didier!

It's too late Mimi, you are married to the Archduke, you must enjoy Didier on the sly.

Now come Mr Snow, let us away to the gloomy joys of the bridal pit where we may indulge in misery and foreboding.

See how the Ambassador carries darling Gibbon off into the sunset? How happy they will be! How happy we shall all be!
