Afaik this is the brand of particularly obnoxious liberals who once had a empathetic thought, decided it was bad and wrong, and then go and write everywhere "i was once far left, but then i got defeated by the factsTM and logicTM and now i'm slightly right of Churchill".
Moralists don't really have beliefs. Sometimes they stumble on one, like on a child's toy left on the carpet. The toy must be put away immediately. And the child reprimanded. Centrism isn't change -- not even incremental change. It is control. Over yourself and the world. Exercise it. Look up at the sky, at the dark shapes of Coalition airships hanging there. Ask yourself: is there something sinister in moralism? And then answer: no. God is in his heaven. Everything is normal on Earth.
Fun fact, on Linux using alt-graph you can get alternative symbols FROM EVERY KEY ON THE KEYBOARD. For example on the polish keyboard using alt-graph + shift + H you get •
Now I don't remember whether it was under T, but somewhere you should be able to get ™.
Also by using alt-graph with and without shift on ~ and 6 you should get logical math symbols. Useful for plaintext math notation.
Usually I don't remember where what is so I just go ham on the keyboard.
I wouldn't encourage anyone to use Windows but if you do then there's a handy little utility app called WinCompose which does this same function.
Virtually every symbol you could imagine comes intuitively and it's customisable if you can copy-paste extremely simple code to make your own command keys for typing a particular symbol, such as where a command isn't intuitive or you need very obscure symbols like a zero-width space.
Sometimes you fat finger while typing and instead of a ł you get some other random character. That's how I found this feature and then I've tried like every key.
The "Post left" is a whole thing. This person has gotten obsessed with the word and has misapplied the label to everyone they don't like. They genuinely appear to think they're on the left and exposing people.
