Atheists, if some guy had a seizure and touched hand on your shoulder and started to do a face palm close to face prayer?

"touched hand on your shoulder and started to do a face palm close to face prayer" - that really doesn't make a lot of sense, but I can figure out what you mean.
I would walk away, if he had a seizure I would call an ambulance.
What does this have to do with the lack of belief in any gods?

If someone had a seizure, I have had adequate first aid training so I  know what to do to make them safe until an ambulance or other help arrives. My lack of belief in gods would have nothing to do with how I reacted whatever the person was doing.

I would probably drop-kick them into next week.

Especially during this pandemic.

Well, if I'm an atheist and I'm having the seizure, I would probably inadvertently bite that guy.

If you mean I am an atheist and I see someone else have a seizure, then another person started to face/palm, I would probably look to see if they have a popsicle stick in their hand?

Otherwise, just sort of stand back to give the seizing person some room, grab some pillows...idk, like for cushioning, call 911?  

Not a medical person here.

probably taken them down in an arm lock
