I suspect that any NWSL or WNT player who disagrees with Sauerbrunn on this knows enough to keep her mouth shut.
Jaelene Daniels was essentially run out of the league for refusing to wear a pride jersey. If you’re a marginal player hoping to make WNT, you’re not going to put that at risk by publicly taking a position that can be branded as anti-gay or anti-trans.
BTW, if you want to keep any job, it is preferable not to go on television and publicly proclaim that you had many of your teammates and do not believe they should be entitled to equal rights. It doesn't matter whether you're claiming that black people should be required to sit at the back of the bus, jews have horns, or gay people should not be allowed to get married or adopt children. You deserve to get fired for telling your co-workers any of those things. It doesn't matter whether you do it in person or through a television screen.
