A fish doesn't know that it lives in water.
Well, yes, but does the fish know that it was born?
People don't live forever. And the world doesn't exist only for the lifespan of a single person who observes the life from the cave of his own mind. People die and to survive the humanity MUST produce newly born human beings. As the sky is blue and the water is wet, the new birth can be given ONLY by a female human cooperated with a male human. Giving a birth for a woman means a lot of risk: risk of health damage and death, risk to lose job, risk to lose all the social activity and social connections, risk to ruin her own entire life. But despite all the risks the birth is urgently needed. This is a strategic need for the entire humankind to survive. And the only encouraging for a woman to risk her life in the name of the society is actually a small ring of a shining metal on her finger, the white dress which she will put on only once, and the hand of a male who is the only possible insurance of her risking her life for the entire humanity to survive.
Do you believe that stripping away these tiny signs of respect (which are probably the only things that keep the life on the Earth), by applying them to all the others who want to behave the same way but are not ready in any way to provide newly born human beings, will encourage the female humans to give more births?
Since we are in the Olympic thread: wouldn't the showing-up of the gays behaving like a couple cause the same effect if the sportsmen participating in the Olympic game, all of them, would be granted with the gold medals despite that the winner was only one? Would the Olympic Games survive as a competition if the "PC" will cause us not to honor the winner, who put their life to achieve the significant results, but to honor all the participants despite their achievements?
