1. the thought that everyone is entitled to their own perspective/opinion/preference
I don't like it but to each his own
The expression 'to each their own' or 'to each his own' (each to their own) is an expression that serves as a reminder that everyone is entitled to their own opinions, customs and worldview and that tolerance is a valuable human trait. This expression can be used in formal contexts or in social ones usually jokingly to make fun of another's personal tastes. It is mostly used to politely say that you disagree with someone but respect their opposing beliefs.
