2. BTW the time of transhumans is coming soon. What will be our answer for the man with two penises that wants to be married with two females? Or a man who wants to be married to some kind of fem-dog or whatever?
p.s. Take it to the limit, and we're ending up with this:

What limits? There are no limits, what about marrying a piece of your wife's finger that's what was left after eating her?
It is only in your scary imagination same as man with two penises, unlike gays and women who always existed, were always oppressed, and only recently got equal rights with men in this "sick" world.
If you fantasize, please keep it in realm of benefits or damage to society, otherwise you will always be lost in this new world, the post communist era. Things were easy in Soviet Block, people were happy, no cataclysms, and no gays either (according to local government there are still no gays in Sochi, lol). Now you have to deal with this plethora of behaviours of human nature. It is complicated and sick.
Did you ever hear about man who wanted two penises? Me neither, so lets skip these silly examples. On other hand we all know that every so often there are people of psychopathic tendencies. Do we need to spell out why such behaviors will never be accepted in any form? Causing suffering, torchering other people for own pleasure, often killing them in process, is highly damaging to any society. To the degree that we forbid such conduct even on our enemies or animals. Especially in today's "sick western world" where happiness of citizens, equality and inclusiveness are cherished.
That goes for the rest of your silly examples. The bottom line is if something is beneficial, neutral or negligibly negative it will be allowed in free society.
If you still miss the "good old fashion" family and their values, watch this:

Nothing better than "good family" tradition of cutting stubborn wife's or daughter's nose off, or killing her all together for the old and traditional honor. In this old fashioned and traditional country 90% of these bestialities happen in family and extended family settings. Make you think why Taliban was so cruel and backward? Well, the taliban members came from these traditional families.
