Nope, you're not "in a bubble" for holding those positions. I see parent poster as listing some things that happen to be popular in the bubble, even if they're also generic american left. When discussing a "bubble", it doesn't matter what the positions happen to be, but how they're discussed, how uniform opinions are, how well they understand where their own positions fit into the contemporary political spectrum of people who share their government, how dissent is handled, etc...

Is that genuinely* what you think?*

Now, this remark is how I know you're in the bubble.
