I like these disclaimers. If someone comes out and states their opinion or bias on a topic, it gives you more context to understand their thought processes and how they came to the conclusion that they came to. It helps you understand the value system that underpins someone's argument.

Ethical arguments can't be made on their own merits, they can only be made in the context of shared value systems. By communicating more about your values, you give someone more insight to understand your ethical argument. If I know where our values differ, I can try to account for those differences. Ripping an ethical argument out of context and putting it in a social vacuum makes it alien and difficult to understand.
