I am sorry to hear you feel this way. as someone who has independent views, I have no idea what the views of the average HN reader are but I'll try to be more mindful of this in the future.
HN has sizable contigents of liberal, left-libertarian, right-libertarian, and conservative posters. And some that don't fit neatly into any of those groups.
It absolutely doesn't have an overwhelming majority favoring any one US political party or candidate .
