Well 99% of cases i just avoid this topic alltogether because people tend to be super butthurt about their religion but imho religion is worst invention of human kind.
Though when it comes to topics like this one , there you talk about countless people risking their lives to help us all (scientists,doctors in this case and/or fireman or rescuer teams in some natural disaster case ) it’s that 1% i dont feel like avoiding this.
Imaginery friends shouldnt be part of this. They do not have a single thing to do with this issue. Our doctors and medical workes and at the end of the day our own hygene and awarness is what’s going to get us through this , not magical beings in the sky wherever someone think they live at.
