The above is one reason (among many) why I totally gave up watching and following sports (Olympics, professional and college) several years ago. At one time I really enjoyed it, but after numerous times of insults and blasphemy (as seen in the OP) I detached myself from it. It was liberating to do so.
Opening day, the playoffs, the finals, the Super Bowl, etc., are all a thing of the past for me.
The Christian has to ask himself/herself how long they will follow that which is evil (3 John 11). I know God works in different ways and in different timing through the believer, but I know every believer should have a so-called line of demarcation within them which says, "If/when it reaches a certain point, I am forever done with this."
"How long will they keep on insulting the precious Lord I believe in, but I will keep on going back for more of it"?
