Welcome to all those new here.
The post settings are like Fb so if you don't want the world to see what you're posting, make sure to set them to "friends only" and your future posts will be set to private.
Reminder: the news feed has a drop down arrow. You can choose to see ALL public posts, or only the posts by people/groups/pages you 'follow.' Conversely, to keep your posts OUT of the public posts, set your profile comments to 'friends only' and post in private groups. (Pages can choose whether or not their posts are visible to everyone or just page folowers.)
The current state of the country can be adequately summed up by the following two things, which are disconnected in every way save their total lack of objectivity.
1. Our National Health Secretary is literally a dude in a dress, who thinks he's a woman, and his background is (wait for it) Psychiatry.
2. In California, it's been deemed dangerous to eat inside. So they have to eat outside, but it's cold. So they set up tents with 4 walls to keep out the wind. So they're eating inside, but it's safe, because it's outside inside.
Hopefully this doesn't completely crush your mood, but this is the level of idiocy that you're now surrounded by. Viva 2021!
Have a happy day. :-)
