What I meant, I'll break it down:
Brodie said it beautifully: "Leftists believe in equality of outcome; liberals believe in equality of opportunity", and so do conservatives, I argue. Truly recognizing the differences between MTF and a born woman means understanding those differences in the context of what this thread is about. This is why I said that both liberals and conservatives can agree on this - because both believe in equality of opportunity. And MTF and a woman do not have the same opportunity together in a weightlifting competition. Leftists, on the other hand, believe in equality of outcome, the outcome in this context being that a transgender person, a male to female, was allowed to compete with other females. However, this ignores the point of the competition. It would make more sense to create an opportunity to compete in a transgender division, but, then it would be apparent that these trans women were not being treated as equal to women... even though they are not. They are in a completely different category all their own, just like everything else in life. Leftists don't like this notion.
Currently, Leftists control the major liberal party in America - Democrats. This is why I made the comment about why America is divided. One side believes in equal opportunity, the other in something fundamentally different. Even though liberals and conservatives are on opposite sides, both can come together in their shared belief in equal opportunity, which shapes many values that are different depending on the side, but can be compromised on because of their shared core. This can't happen with leftists vs conservatives.
