Or the natural perforation of her hymen left plenty of room. Or her hymen was particularly elastic. Or she was aroused enough that the lubrication present meant it didn't need to tear. Or any of the myriad other explanations that all combine to form the conclusion of "hymens don't always break during sex" that don't rely on micropenises.
Outside of really extreme cases (on either end), dick size really doesn't influence that much about how enjoyable sex is, and I say this as somebody who's larger (in both respects) than 99.9% of North American dudes. Angling thrusts properly is generally going to be much more pleasurable than simply penetrating deeper or stretching further, and the vast majority of women rely more on external stimulation than penetration to get off. And that's without even considering the emotional angle of things, which can often do just as much (if not more) than the physical experience to make somebody feel good.
It's not so much hate for hymens as it is hate for the idea that the presence or absence of a hymen means anything significant. Even if we presume that virginity is a meaningful concept (which is a big if), the hymen is not at all a reliable indicator of it, and treating it as being significant (to the point of some people - even in America - having doctors perform "purity checks" on their daughters) is therefore foolish at best. At worst, it gets downright abusive.
