As cited previously...
Numerous surveys have proven that heterosexual spouses are much more faithful and monogamous compared to homosexual couples. E.g. In “Sex in America: A Definitive Survey” 75% of husbands and 90% of wives claim never to have had extramarital sex. 83% of heterosexual couples were monogamous, but less than 2% of homosexual couples were monogamous. (Robert Michael, et. al., “Sex in America: A Definitive Survey” Boston: Brown, Little & Company, 1994, pp 101-107)

Oh dear DM, get a grip. Another way of looking at this data is that homosexuals are simply more honest about their sexual behaviour. As for married heterosexuals, if someone asked you whether you had been unfaithful to your spouse, and you had been, would you really tell the truth, and expect everyone else to do the same? Statistics based on what heterosexual spouses "claim" to do, instead of what they actually do, in the dark when you are not looking, are not worth the paper they are printed on.

Grace, my dear woman...there is none so blind as those who will not see! Your argument is becoming less believable with each posting.
Read the stats, Grace, read 'em and weep!

Have you been unfaithful to your spouse DM?

Unequivocally and categorically – No! By referring to another debate, you’ve wandered from the topic at hand, and let's not waste people's time.

You have missed my point DM. It was you who quoted dodgy statistics on homosexual and heterosexual promiscuity, presumably to lend support to Bill's thesis on the "nuclear family", and your argument against homosexual marriage.

In responding to my question as you have, you have made my point, as outlined above. Your denial of extramarital infidelity is very emphatic, and entirely predictable, thank you. Why should we believe you are telling the truth? The question therefore remains, why should anyone believe the 83% of heterosexual couples, quoted in your statistics, who also claim to be monogamous.

But moving right along, today in the "Australian" you have published your letter in response to another online opinion ("Denying Christmas is political correctness gone mad!"), and we now know that you are Donna Murphy of Petrie Queensland. Hello Donna, take a bow.
