I am not complaining. I don't trust myself with the responsibility anyway but I have 500+ and I cannot down vote stories.

I used to avoid voting on comments on my phone for a while because I was afraid I'd end up downing with my fat fingers but they've fixed it with an undown link when I down vote. Maybe they've relieved me from the responsibility of down voting stories?

I don't know how I feel about down voting because there is always a desire to down vote dissenting opinion.

tl;dr that's for comments afaik

1225 karma here and I still can't downvote stories, just comments.

that's for comments, downvotes for stories don't exist.
