July 2, 1990, The Roman Catholic church condemned Madonna's as "Blond Ambition" concert as sinful.

Not that it's a good thing to earn the wrath of the Roman Catholic Church, but it speaks to what a big deal the Blond Ambition tour was that the Vatican's official newspaper, Osservatore Romano, declared the show sinful – a more or less unprecedented decision. 

Madonna's legendary speech in Italy as seen in Truth or Dare.

I am an ltalian-American, and I am proud of it.

Proud of being an American because it is the country I grew up in,

the country that gave me the opportunities to be who I am today

and a country that believes in freedom of speech and artistic expression.

My show is not a conventional rock show but a theatrical presentation of my music.

And, like theater it asks questions, provokes thought

and takes you on an emotional journey.

Portraying good and bad, light and dark, joy and sorrow,

redemption and salvation.

I do not endorse a way of life but describe one,

and the audience is left to make its own decisions and judgments.

This is what I consider freedom of speech,

freedom of expression and freedom of thought.

Every night, before I go onstage,

I say a prayer not only that my show willl go well but that the audience

will watch with an open heart and an open mind

and see it as a celebration of love, life and humanity.
