The reason you're getting downvoted has nothing to do with the "progressive narrative" and everything to do with the fact that your posts are off-topic. Political complaints about Mozilla from a left perspective would be equally irrelevant. Availability of browser add-ons is obviously not a political issue.

Conservative comments are not removed, bad-faith discourse probably gets flagged. I've said some pretty spicy things here and never noticed an issue. Check yourself maybe?

Are you kidding me? HN is one of the most transparently conservative comment sections on the internet.
