I think what /u/FrootLoops means to say is that while the downvoter is anonymous, the commenter isn't. The protection scale is different for one who voices his opinion through commenting, and one who voices his opinion through voting, which creates inequality.
Both options remain a choice, no one is forcing anyone to do anything. Comments can be about anything and cannot be seen as irrefutable evidence of a vote and thus even if a comment is made, the vote remains anonymous.
