Quotations
This is a matter of degree, and depending on the extent to which a given fan indulges in anything more than local club activity he may be distinguished as an actifan (as opposed to passifen); stress on crifanac rather than congoing, among actifans, is the chief extensional distinction between trufans and confans.
