Remember that the existing consensus was also created by scientists with political and social motivations who made plenty of assumptions about gender.
A challenge to the status quo isn't automatically biased just because it challenges the status quo.
These "red line" commenters are so blinded by their own purity tests that they can't see they're actually supporting the greater genocide. Every thread here on lemmy is full of them, and they all make the same case, but they refuse to acknowledge the actual reality, which is that not voting for the one person who has an actual chance to beat Trump, they're actually supporting him. Not as much as they would if they actually voted for him, but still significantly.
If Trump wins by a narrow margin, it will be because of these red-liners who valued their own purity over the lives of others.
