I think this site isn't quite like Wikipedia, but their advice about writing with a neutral point of view is helpful, especially their advice about using contentious labels.
When you must use a contentious label in order to address the question, I'd follow their suggestion to use in-text attribution. I think that helps push the responsibility for the contentious label to the reliable source and not you.
If the label is not material to establishing the answer to the question, I'd drop labels alltogether.
