Of course the Bible doesn't say women should have "no say in religion," but that's not the issue. The issue is whether or not women are to lead or teach men in church. And the Bible is very clear that women are not to teach or lead men in church:
(1) Let a woman learn quietly with all submissiveness. I do not permit a woman to teach or to exercise authority over a man; rather, she is to remain quiet. For Adam was formed first, then Eve; and Adam was not deceived, but the woman was deceived... [1 Timothy 2:11-14]
(2) As in all the churches of the saints, the women should keep silent in the churches. For they are not permitted to speak, but be in submission, as the Lord also says. If there is anything they desire to learn, let them ask their husbands at home. For it is shameful for a woman to speak in the church...
If anyone thinks that he is a prophet, or spiritual, he should acknowledge that the things I am writing to you are a command of the Lord. [1 Corinthians 14:34-35, 37]
