If you are stupid enough to believe otherwise, you do not live on planet Earth. Coercion takes many forms, and cooperates with female selfishness, but it is plainly the main reason. And I find it significant that the apostle of selfishness, Margaret "there is no such thing as society" Thatcher, was a committed and extreme pro-abort who saw nothing wrong with abortion at 27 weeks, and who corrupted her whole party till there was no place in British politics for anti-abortion forces. If you want to lie to yourself that there is anything in there besides a collusion in squalid and short-term selfishness between boss and employee, boyfriend and sex object, you are, again, lying to yourself.
