We are not questioning your ability to discriminate. This conversation is like this:
Q: Why would a club want to keep women out on Saturday mornings?
A: Its their club, if they want to keep women out they can.
Q: Well, ok, sure they can, but seems pointless alienation. Why would they want to keep women out on Saturdays?
A: In my business, sometimes I discriminate against old people!!
Q: Uh, OK, that's strange I guess, but why do you want women off your course on Saturdays?
A: This has nothing to do with race.
Q: OK, I know that. I want to know why you don't women on your course with you. Its weird.
A: WHAT ARE YOU A GOLF CLUB MANAGER
We are not questioning your ability to do so legally. We are not questioning if there are legitimate basis for other discrimination, nor are we questioning that discrimination still exists in our society, or that members of this board take part in it - rightly or wrongly - from time to time. However, some of us don't see the point in alienating half the population of the earth for no gain, and would like to see the practice ended.
We are not against discrimination per se. We are against pointless discrimination.
We are asking a simple question:
Why have the rule?
