Don't have time to do all of this but I'll start with this:

A major study by Bell and Weinberg revealed that 78% of male homo- sexual "affairs" (relationships entered into with an intent of commitment) lasted less than three years.

The study was done in 1970, long before the AIDS crisis and the resulting shift in attitudes about long-term relations in the gay community in the United States. It was a self-selected study done just in San Francisco, advertised mostly in public places such as gay baths.

The book by Bell and Weinberg says of itself:

It should be pointed out that reaching any consensus about the exact number of homosexual men or women exhibiting this or that characteristic is not an aim of the present study. The nonrepresentative nature of other investigators' samples as well as of our own precludes any generalization about the incidence of a particular phenomenon even to persons living in the locale where the interviews were conducted, much less homosexuals in general.

In other words the numbers can't be relied upon to say anything about gays either in that part of SF, or as a whole. The study was never meant to do that.

So much for that number.

Maybe somebody else would enjoy tackling the next?
