Jason, I suppose it depends on what degree of hate you are writing about and what words you use...how strong your theme/idea is. If you wouldn't want your child to read it, then don't post it here. That's all I can say to help. Here's the link to the guidelines for the site if you didn't get the chance to read them yet. Hope this helps. http://piptalk.com/pip/guidelines/rules.html
Also in the Member's Area/Help section, there are explanations to the forum ratings that might help you decide what to post and where and what not to post at all.
Good luck! And if in doubt, you can always email a moderator for help and advice.
