Anything but heterosexuality has ALWAYS been considered perverse, sick and/or sinful by all the cultures of this planet.
From Google: In a nationally representative, online sample of 3145 men and 3283 women, 3.6% of the men and 1.4% of the women identified as gay. A further 5.5% of the men and 7.4% of the women identified as bisexual.
Even if these numbers were accurate, and I don't think they are, that leaves 95% MINIMUM of the human race as normal bisexual. I think the numbers are inflated. They were probably from a survey and surveys are the rock bottom WORST source of information.
The ENORMOUS coverage that this HUGE minority gets is what's sickening. The MEDIA glorify them, no one else.
In the end they don't reproduce (usually) and they die out. THEN they get to meet their Maker. Shudder! Try and explain THAT to their Maker.
A few years ago, CDC did a survey which identified 1.8% as homosexual. I think 0.4% were bisexual.
