1 Corinthians 11:5 is not addressing conduct INSIDE a church.
What is INSIDE a church? The house of God and the church of the living God? Pillars of truth? Pews of holiness?
Are you really one of those that thinks the church is a building made with hands? Is that the only time you are ever in an assembly of the saints, or gathered two or three together in His name?
Women can speak and prophecy outside the building but not within? Are you therefore promoting curbside women ministries?
Where in Scripture do you read that women may only prophesy outside? Or only in their own homes? What about when all assembling was house to house?
And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart, Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved.
Did they only hear the voices of men speaking and praising God? Did Anna get barred outside the door, before she could speak of Jesus and His redemption?
But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth, howbeit that women shall not do so in the churches.
1 Corinthians 11:5 is not addressing conduct INSIDE a church.
Once she enters the church she must be silent.
Since you've taken the bait, stand forth like a real man and answer the questions demanded of you:
Hand signals only? No
'God Bless you'?
I'll bet you like shooshing women, especially little girls. Do you practice your silencing
glare 
at home in the mirror?
So, little boys can speak up anytime they want in church, but not little girls? Or is it just a rule for women?
"Enjoy talking in church while you can little Suzy, because once you're of age, no more speaking out loud in church." "Yes Mommy. Praise the Lord everybody!!!" "Good girl Suzy. Get it all out while you can."
What about man-idiots that don't know how to stop talking, when something important is being said elsewhere? What about in the hallways, or are they sacroscantified too?
A woman can certainly shoosh any idiot disrupting the service, since shooshing is not speaking. Slapping too. Man-Slapping good, Woman-Speaking bad.
“Is not my word like as a fire? saith the LORD; and like a hammer that breaketh the rock in pieces?” (Jeremiah 23:29)
Oh yeah, I truly would love seeing you try that fiery indignation on my rebel Syrian wife.
Oh yeah.
"Hey baby. See that guy over there? He says it's a shame for you too speak in this building. He says all women ought to just shut up as soon as they walk through those doors." "Really?" "Yeah, really." "Alright, let's go have a talk with him." "After you, my dear."
How many think I am joking with this last part?
