I'm not wrong. My comment was that you could choose to blithely remark OR post links to support your claim, which would be the more productive route.

Instead, you have doubled down and chose to continue making blithe remarks like "gravity doesn't need a reference."

You are wrong because it's not a claim. The pathophysiology of Covid is hard science. Gravity existing is not a claim either. No need to support either of those with ref's is because they are easily googleable. It's a waste of people's time.

If it's not affecting the brain and nervous system why are people opening up clinics specifically for that? https://www.the-scientist.com/news-opinion/covid-19s-effects...

People open up churches to an invisible man in the sky.

Who knows why people do what they do.

Again, no sources to back up any of your claims. As Hitchens once famously claimed, "What can be asserted without evidence can also be dismissed without evidence."
