If it is an illogical post which I do not agree with, I shall downvote it. If it is poorly written and I disagree, I will downvote it. If it is poorly written and I do agree with it, I will upvote it. Et cetera.

I don't bother too much with the point system so we can keep the quality of debate and discourse as high as possible..

I don't have an answer because I don't vote arguments up or down. Instead, I argue arguments "up or down" with my agreement or disagreement.

If fact, I think the makers of this site should require someone to present a responsive argument before they are allowed to vote an argument up or down. Lacking that, I think it should be a custom among CD users to do so. Then it would be obvious why the vote up or down was made.

I vote down if someone makes an irrelevant point or if they support homosexuals.

I don't really up or down vote anyone, because I just want to keep the quality of debate and discourse as high as possible.

I rarely ever down vote regardless what the argument. I usually only up vote if it is a good argument and on my side.

I will only up-vote if the argument makes a particularly well thought out or astute point.

I will only downvote if the argument is exceptionally stupid or lazy and thus irritates me sufficiently to motivate me to downvote it.

Most of the time I don't bother with voting either way. I post arguments, those are my votes.
