I think it happens all over and sometimes it really kind of depends on how long your argument is and the general impression people get from the first part of it. If you’re making a devil’s advocate argument in the first part, but then the twist comes later on, people are going to think your first devil’s advocate argument is the gist of it and downvote you based on that alone without getting into the nitty gritty. If people can form a knee-jerk reaction within the first few seconds of reading your post, they will, nuance gets lost.
I tend to leave really long comments, sometimes with a bit of raw information, so I see how that can be the case. Some communities like reading all the way trough, but I'm pretty sure that in some places, they don't even read my username, just vote based on my avatar.
