Nowhere in Acts do you find the term "Baptism of the Holy Ghost" in connection with speaking in tongues.
The baptism of the Holy Ghost is related to salvation and not tongues (1st Corinthians 12:13).
There is NO command in the Bible to speak with unknown tongues.
A person who does not have the Holy Spirit is not saved (Romans 8:9 and 1st John 4:13).
A wicked generation seeks a sign (Matthew 12:39).
The tongues movement of today is NOT Acts 2 tongues but the CARNAL tongues of 1st Corinthians.
