Notice how they lack any outrage toward girls who do porn/onlyfans/etc right when they turn 18. It's only the relationships they attack.
This is because a girl who just turned 18 still has some hope left for her. If she hasn't been fully turned by feminism and finds a loving partner that's older and more mature than she is, she will adapt to his moral compass.
They would prefer that she goes straight to college, gets brainwashed into becoming a feminist, has multiple partners by the time she graduates, is stuck with endless debt and haunted by the abortions she had along the way.
