Perhaps it is because the Bible does not support it. Does the Bible support sex for pleasure amongst straight couples, anal sex amongst straight couples, and even oral sex amongst straight couples? Where are Moscow's bans concerning them, and condemnation by forumgoers here of these practices? Do they simply fly under the radar and remain unnoticeable, because these are not gay couples practicing them?
In short, there appears to be little integrity with this law considered independently, and with the government which created it; which does not explain the basis for its intention - or if it does, does not apply the same principles with which it prohibits one aspect of some people's lives, to all aspects of all people's lives equally, which themselves violate the principles all the same. The same lack of integrity, which one would think essential to maintaining sound governance of nation as well as individual, can be implied in those who vocally support this policy; but who do not offer complete, honest, and thorough if even self-deprecating analyses as to why the policy addresses a unique "problem", as they see it, versus a "problem" possibly applicable universally to a much wider range of members of the human species, most of whom are insulated from condemnation along the same lines, simply by being of a category artificially designated to be of absolute significance to the topic at hand.

The topic of the ubiquity of anal sex practice across populations, both gay and straight, and either independent of or dependent on country or geopolitical basis or religious influence, has not been fully examined and successfully rebutted. What statistics can a supporter of this 100-year ban pull that say that 100% of straight couples have had 0 instances of anal sex in their lifetimes? Is this even a realistic number? In fact, the most realistic that I have personally encountered is that 25% of heterosexual couples have had anal sex... and how many couples does the average person have in their lifetime? Numerous.
The reality that anal sex is not unique to gay couples is jarring to the anti-homosexual polity. In addition, oral sex is practically universal across all types of sexual orientation, and in a variety of positions, and neither oral nor anal sex are conducive to human reproductive capacity... obviously.
Anothe r approach is to consider the widespread use of contraceptives among straight couples in the past few decades. Not only are people having sex out of wedlock, they are having sex while intentionally deterring the possibility of having children. They are having sex for pleasure. Where is the 100-year ban on this aspect? (cont'd)

Countries that are able to sit down and speak with each other, rather than to each other....... It seems can only gain, in having good results.
