Illinois Bishop Exorcises the Demons!

In response to Illinois Governor Quinn signing Illinois' marriage equality bill (woop!), some absurd Catholic Bishop staged an exorcism, saying:

"I exorcise you, every unclean spirit, every power of darkness, every incursion of the infernal enemy, every diabolical legion, cohort, and faction, in the name and power of our Lord Jesus Christ. Be uprooted and put to flight from the Church of God from souls created in the image of God and redeemed by the precious blood of the divine lamb."

Now, 90% of what I know about Catholicism I learned from Sister Act, Wikipedia, a Catholic ex-girlfriend, and feminist critics, but does this Bishop think that gay people are actually possessed by demons?  Doesn't that literally demonize us?  Or, is it a super important, totally civil distinction to clarify that gay people aren't demons, it's just that there are demons inside us. Making us be gay.

And, is it at all considered unbecoming or, say, a breach of confidentiality and boundaries to exorcise people publicly without their consent? I mean, trusty Wikipedia notes that an exorcism should "never be broadcast in media but treated with the utmost discretion," so.

Rude!
