I am indeed American. However, the reason I assumed you propagate black and white thinking is you constantly refer to the extreme:

You could however keep worrying for the rest of your life and feel miserable, spend time for all sorts of preparations, become germophobic, restrict your life decisions and become bitter.

But while you fear and hide, the world is moving on without you.

of course a covid related community will be full of people who wear masks under a shower.

You act like anyone who recommends taking precautions is a crazy germaphobe. If you want to sound reasonable, use reasonable language.
