When I fit this pattern over my comments and irl connections, I get something like:

I have some pretty strongly held, but also probably divisive opinions, that I’m afraid would push people away from me if I voiced them to my irl people.

So the thought / emotion is feeling limited irl, and feeling less limited in an anonymous Internet forum. And even occasionally validated in an Internet forum when you find someone that agrees with you. (Or sometimes, when I’m proven wrong, I get something to think about for a little bit.)

Interesting thought exercise, thanks.
