In Washington state at the very least this isn't true. The default parenting division is 50:50, and there would need to be strong extenuating circumstances for a parent that wants 50% parental time to not get it. In my experience men are less likely to seek 50%. Equal co-parenting is hard, it pretty much requires that you live in or near the same school district as your ex. Being a weekend or summer co-parent doesn't have the same constraints. It won't be the right solution for every case, but it is always available. I know several single dads raising kids with little or no co-parent from the mother, but it is the exception, I know far more who went with "every other weekend plus one midweek night"
