I was a new user. I hold many minority opinions (including ones diametrically opposed to those you have named as critical points of HN consensus, particularly on the issue of political ideology), and have expressed them from very early in my time on HN. I haven't been downvoted out of visibility.

I suspect that you are both misattributing the cause of the karma hit your earlier account took and falsely generalizing from that misattribution.
