Hey!
This is a really sensible question, and in general I don't think you necessarily have to avoid topics that touch on social or political issues altogether, particularly if it is something you are passionate about. However, I would usually lean towards something that is clearly framed as a legal or practical reform rather than a purely political one.
The key thing that firms are assessing with these questions is your ability to identify an issue, explain why the current law is problematic, and propose a clear / well-reasoned solution. Therefore, topics that are a bit more technical (e.g. within regulation or procedural reform) can sometimes make it easier to focus on the legal reasoning without your answer becoming more values-driven.
However, if you do choose something with a social element, it is usually best to keep the tone quite balanced and analytical - I would acknowledge different perspectives and focus on the practical impact of the reform, rather than presenting it as a strongly opinion-based argument.
Overall, I don't think you have to avoid those topics entirely, but some people do find it slightly safer and easier to demonstrate their reasoning with a more "legal" or technical reform
