It makes sense, in informal contexts, to espouse a contrarian view, particularly if it is the opposite to what you actually hold to be true and the issue at hand is frequently disputed. In doing so, one can strengthen the future presentation of one’s own real position using information or strategies garnered from your interlocutors’ responses (assuming that a contrary discussion elicits more of potential value than one conducted in agreement).
In short: argue against yourself when it doesn’t matter in order better to argue for yourself when it does.
There can be plenty of signalling reasons to publicly support contrarian positions. For example, they can help generate discussion, make it seem that you know something which most people do not, help solicit support from those who support minorities—and so on.
