Why are televangelists afraid to preach on these verses '1Cor.14:34-35'?

You're misinterpreting the Bible. Paul was addressing those certain Corinthians in that particular time. It is not stating that God doesn't call Women to preach. That is a lie. You are interpreting this incorrectly. Without God's spirit to open your eyes...you will never understand the full magnitude of God's word no matter which scriptures you decide to pick and choose for your own purposes..
