What would you use for a synonym for based? I keep seeing that used. I always thought it was just some alt-right meme bullshit, but I'm learning I was wrong. I still don't get the use. My mind always thinks "based on what?"
"Based" is typically used to describe someone who says/does something without caring if they'll be judged for it. Most commonly, it's shorthand for "That's a controversial opinion and you are bold for saying it, but I agree with you." It turns the previous sentence into an adjective, which is a little weird but it makes sense eventually.
So if I had to choose a single word as a synonym, I would say "Bold".
