Irrelevancies

There seems to be a high level of use of irrelevancies these days.  I remembered the probability statement of relevancy/irrelevancy I read one time:

If P(AIB) = P(AI~B), then B is irrelevant to A, where A and B are events.  

But who wants to get into that?  If I want to say that men are some sort of "superior" to that other sex, I have not been thinking of probability but of my audience.  They seem to be the type to be happy to forget what we have been talking about and switch to discussing the equality of the sexes or the superiority of one of them.

I can try to appear intelligent and brave and capable and to use my capacities to advance us all in some new way.
