Stalinists don’t believe all of the bullstalin they spew. They just say whatever it takes to get you to accept their way.
The “science” of genetic homosexuality are just for those who will be swayed by such arguments. They really believe in an end to ALL moral judgment over ALL sexual pairings, regardless of sex, age, relation, martial status, number, or species of partner(s). If they explain that someone people “can’t help themselves”, well maybe some will surrender to the group think. Transvestitism is not natural. We are born naked, there is no gene to “wear the other’s sex’s clothing”. Clothing is determined by culture and fashion.
The goal of “global warming science” is to reduce the size and production of the West. China and India are permitted to continuing using so-called “fossil fuels” and burning tires and coal. But some well-intentioned Americans are willing to use crappy toilets, low wattage light bulbs, and short range electric cars “to do their part to save the planet”.
Abortion serves the “zero population growth” mindset of the Left (who said 42 years ago that we would be facing a population explosion). It also serves the “do as thou will” philosophy of the sex positive hedonists. Why worry about the next generations when the goal is to live for today as thou wants?
Don’t look for consistency from Stalinist minds.
