Too funny, Mimsie!!
I thought it very appropriate and all Facebook users would think it a great idea.
No Facebook here - but I loved this.
I feel you understood the meaning of this. If you don't like something on Facebook you can delete it but it would be so much better if one could dislike it as well and I guess anonymously would be even better.
Oh that's funny! I'm laughing here.
It's just a great pity that this option hasn't been made available on Facebook.
