I end up writing "destroy all communists" in different languages when signing yearbooks and senior portraits
Do you enjoy looking back at your work?
Not really, they're horrid to look at
Though you are free to think whatever you wish of political issues, you shouldn't be writing such opinions on other's possessions. They may be the ones who get the flak for it later if someone is able to read what you wrote and associate it with them.
I don't care and I'm over them all. I doubt anyone remembers what I wrote.
It is better to save your opinions or a more appropriate setting that writing them on something like this.
