Make that "some protestant church groups ordain women all the time".
Those protestant denominations and non-dominational churches who still believe that the divinely inspired Word of God is the final authority on faith and practice don't ordain anyone who doesn't meet the qualifications laid down at the beginning by the One who is the divine Head of the Church and the sole, final authority on how it is to operate in a hostile world.
BTW, not everyone takes every word uttered by St. Paul as the revealed Word of God.
