You are stuck on that point and it doesn't help you. If anyone was to summarize 1 Cor 14, they would say Paul was against speaking of tongues in the church because it was all confusion not unless it was interpreted. So Paul was for something that everyone would understand.
What happens today is in total contrast of what Paul is saying in 1 Cor 14. People speak incomprehensible words and no one interprates. So im still right as per 1 Cor 14 to castigate todays tongues because no one understands them- Paul would have done the same.
Speaking in tongues is a gift and interpreting the spoken tongues is also a gift as per:
1 Cor 12:
7Now to each one the manifestation of the Spirit is given for the common good.
8To one there is given through the Spirit a message of wisdom, to another a message of knowledge by means of the same Spirit,
9to another faith by the same Spirit, to another gifts of healing by that one Spirit,
10to another miraculous powers, to another prophecy, to another distinguishing between spirits, to another
speaking in different kinds of tongues,
a and to
still another the interpretation of tongues
If you claim that speaking in tongues is a manifestation of the gift of HS and every Christian should do it, so is the ability to interpret those tongues and every christian should be able to interpret tongues- don;t you think so?
Praying in tongues (spirit praying on one's behalf) is a private affair and i have no issues with it, Paul didn't have any issues with it. Christians don't pray in public- when you pray, close yourself in your closet and pray privately. People praying privately should not be our concern - whether they use known or unknown language, it shouldn't concern the public and we shouldn't be discussing it here. And why should anyone shout when they are praying privately? they can as well pray silently in their spirit.
This is the context of praying in tongues or in the spirit:
Rom 8:25But if we hope for what we do not yet see, we wait for it patiently. 26
In the same way, the Spirit helps us in our weakness. For we do not know how we ought to pray, but the Spirit Himself intercedes for us with groans too deep for words
I repeat, what we see in our churches today has nothing to do with God.
