Pooncrew, I follow the guidelines given by Fizzer (see the [?] thing below the thumbs):
You should upvote or downvote based on whether you think the general WarLight community would find the content of this post interesting, enjoyable, or useful. Be careful not to let your own prejudices affect your voting.
Given that guideline, I can totally understand why others might not find this OP interesting, enjoyable, or useful, hence giving it a downvote.
If a post was moved to the wrong forum, why not just ask the mods directly, to move it to the right forum? Perhaps it was a simple mistake. Instead, you go on to make petty insults.
You complain about "The whole point of a forum is to open a dialogue, not to censor someone you don't agree with". I agree with that, but a) you're not being completely censored, just hidden under a sub-list, and b) I don't see you taking responsibility and fostering "interesting, enjoyable, or useful" dialogue very often. Do you take the time to downvote troll comments? Do you refrain from using petty insults pointlessly (which makes you look more like a troll, btw)?
Be the change you want to see.
