Issues & Controversies is an excellent go-to resource when writing a persuasive essay. 

Keep in mind that an effective persuasive essay begins with a strong and arguable/debatable thesis statement. An arguable thesis avoids the "duh" reaction. For example, if your main idea is something generally agreed upon (e.g., schools should not tolerate bullying), then there is no need to persuade your audience with your argument. 

To approach the opposing point of view of your topic, you may need to think about what you're looking for with a bit more nuance. For many topics, your opposing viewpoint article won't argue that the issue you've selected is totally invalid or isn't a real issue.  Instead, look for articles with a viewpoint on a specific proposed resolution to an issue or a specific policy related to it.
