I honestly had no idea that anyone "left of center" felt they couldn't openly share here, as I have always mentally categorized HN as a leftist echo chamber (hopefully that's not too blunt - it's just my honest perception).
I naively assumed that it was only those more right-of-center that felt their worldviews and opinions were unwelcome here, judging from the instantly dead posts I see of anything remotely right-aligned.
From your short share, I see that the echo-chamber is unwelcoming to a much broader sphere of humans than I realized. I find that super helpful to understand - so thank you for sharing.
