Going out with Fans of other Clubs

Bit of a random one, but do any of you lot go out with/date/smash one through a fan of another Club?

I don't just mean like one of these Man Utd or Liverpool types from around here, I mean like actual fans of other Clubs that actually go to watch their team.

Obviously, I know you wouldn't go near a viler or a dingle, but which kind of a club, other than Blues is deemed as acceptable?

Asking for a friend.
