Is it funny or offensive?
Yes.
To someone who thinks that the whole Pentecostal "slaying in the spirit" thing is bizarre already, it's kind of funny.
To someone who takes their worship seriously, and is often mocked even by other Christians, it can feel just like one more attack. Is it a harsh attack?
Ever play "Rock, Paper, Scissors"? The first time someone flicks your forehead or wrist, it doesn't hurt. 10 or 15 minutes later, it feels like a sledgehammer.
In the 80s, I knew people that suddenly got sick, and died of AIDS. We didn't understand much, but I saw a friend wither away, get dementia and forget who I was, and die at an early age. At that time, people would say,
What does GAY stand for? Got AIDS Yet?
What do you call gay musicians? Band-AIDS
What do you call gay guys on rollerskates? Rol-AIDS
Was it funny? Moderately. Did I laugh? No. It felt cruel, ignored people who watched their sons, fathers, and friends die, while the government sat by and did little.
I was once involved with a Pentecostal Church. I saw people get "slain in the Spirit", people physically healed, people "profecy" where God spoke through them. I speak in tongues, and have was with a group that all seemed to sing in unison. I believe differently now, but to those people, their belief in God was their all. It was the most important thing to them.
So, a few people may be offended, especially with the tone of the music itself, that has a pretty negative energy. Expect it, acknowledge it, and understand it.
Were you to have lost someone to 9/11, you would probably be offended with a 9/11 joke, or someone who made light of dead soldiers during the war if your best friend was sent back in a body bag. Put yourself in someone else's shoes, and it's easier to understand, rather than judge the validity of being offended.
Although it slightly worries me that people buy into that kind of thing.
