"When one identical twin is gay, less than half the time will the second identical twin be gay."

52% is not less than 1/2.

Hmmmm. Perhaps I should have said around half. I guess I was thinking about lesbians at 48%. So gays at 52% and lesbians at 48%. Doesn't sound like a very persuasive argument for either predilection being genetic.

Wait a minute! I went to the link in post 91 and his statistics show far lower percentages. Those darn American researchers.......they just continue to prop up the gay agenda.

"52% is not less than 1/2."

1: Spunkets, I take it you are ignorant on how PROBANDWISE concordance is calculated? 52% probandwise concordance actually is less then 1/2. The following wikipeda link explains how "probandwise concordance" is calculated for you...

2: Bailey's study which had a 52% probandwise concordance was flawed and Bailey admits it himself(in the quote below). They advertised in gay periodicles which gave them a biased sample. Bailey's most recent study used a more random sample out of an Australian town registry. With a nonbiased sample, there was only a 20% probandwise concordance for male homosexuals identical twins and 24% for lesbian twins. For those who don't feel like reading the paper or doing the math, 20% probandwise means only 3 out of the 27 pairs of identical male twins had siblings who were both gay. This study pretty much blows the whole "gay gene" theory out of the water.

Here is a quote and link from Bailey's paper that backs up what I am saying...
"The most striking difference between our results and those of past twin studies of sexual orientation concerns the probandwise concordance rates. In a recent review the lowest concordances for single-sex MZ samples were 47% and 48%, for men and women, respectively.In contrast, our MZ concordances were 20% and 24%, respectively, for the strict criterion that is most similar to those used in prior studies. These rates are significantly lower than the respective rates for the two largest prior twin studies of sexual orientation: for men, 52%, [chi] (1, = 550) = 8.2, < .01, and for women, 48%, [chi] (1, = 1,115) = 4.3, < .05. This uggests that concordances from prior studies were inflated because of concordance-dependent ascertainment bias."

Finally, it is amazing to me how the 52% number STILL gets thrown around by "pro-gay" advocates, while the better and more current study is ignored. It kind of reminds me of Kinsey's old 10% of the population is gay myth.
