That is great to see. There appears to be a lot of Catholics in the Olympics. Usain Bolt is one Catholic that comes to mind, making the sign of the Cross before every race.
But I have to agree with Daegus that the Olympics are demonic. That's not to say that it's sinful to watch them, some olympic sports can be entertaining. But there are numerous anti-Christian elements in the Olympics. For instance, the name “Olympics” comes from Mount Olympus, the home of the Greek gods. The original Olympic games were started in 776 B.C. to honor the chief god, Zeus. The Olympic logo (the five rings) looks a lot like the eye of Osiris, the Freemasonic symbol that can be found on the back of the US dollar bill. And what's more, the Olympic 2012 logo really says "Zion". Have a look at what the logo actually says if you mess around with the so-called numbers a bit:

Something else about the Olympics that really turns me off is the concept of all the nations in the world coming together to compete. Something about that sounds like the nєω ωσrℓ∂ σr∂єr, where there will be a one world everything.
And then you have feminism being promoted (with immodest dressing to go along with it), tributes to the anti-Christian band "The Beatles", and gαy singers perform at the ceremonies. The ʝʊdɛօ-Masons are control freaks, they have to run everything, even sports. And they are definitely present at the Olympics.
