I didn't vote at all on this post but I downvote and don't comment all the time. If a post has a combatative tone or it is just a stream of assertions without facts (e.g. this post) it's generally best to not comment on it even if you disagree. Trying to always comment just ends up being impractical and you have to pick your battles.
