Did you create Bikini Bottomies page? I read the article, and for me, Bikini Bottomies mostly good, and not truly evil. I think, their antagonistic nature was due to their tendency to create a group of angry mob when enraged, stupid, and mostly prefer commit actions without thinking twice and never thinking about the consequence for their actions. They also often had misunderstanding, even easily provoked with trivial problem. They may often pick on non fish character for no reasons but not always. In some case, they also did it out of grudge, especially to Squidward.
