This is my experience as well! I usually reflect on my unpopular comments and realize I could have been more considerate or worded things less rashly... Or my viewpoint is just unpopular.
I find it genuinely difficult to relate to the other comments on here equating downvotes to oppression or even violence.
If anything, my hope would be that Hacker News becomes MORE strictly moderated via downvotes, and maybe even starts banning some non-tech oriented politics. Now shower me with downvotes, 500+ karma daddies, to show the little ones it is okay.
