It´s completly stupid to believe that. But there is a cultural thing going, that´s obvious.
Women like to be a tease, and sing things like " I don´t need a men",telling they are bisexual or lesbian is the extreme of being a tease. This of course makes only men want them more.
But even if women are fvcking each other because they can´t find a high value men it´s their problem. They will soon realize that it´s not the case that there aren´t valuable men out there, these women are simply not good enough to compete against high quality women for the best men. So they could pretend they are lesbians as a matter of pride... But hey women can´t stand each other, anyone who knows women knows this... so they will get tired of each other pretty fast.
It could also be the case that lesbian activities are forbidden and we know women are emotion junkies.
That´s why you really need to be the bad boy, treat them like garbage AND THEY WILL THANK YOU AND LOVE YOU FOR IT etc... Sorry this is the real world.
Men are designed to handle pressure and stress, women aren´t, if men start also playing mind games we win by a mile.... DO THE FEMALE GAME; TELL THEM THEY ARE NOT YOUR TYPE; MAKE THEM QUALIFYING TO YOU ETC. IF MEN INSIST THIS **** OF PURSUING THEM EVEN WHEN THEY DUMP YOU THEIR POWER WILL ONLY INCREASE. Mystery is a genius, too bad most people don´t realize it.
