been a while since I came here and it is still a bashing ground for Christians

Christianity has been around for a long time and very much of Christianity's history is that of European history, both good and bad. Some time around 300 AD Emperor Constiatine (whatever) stopped presecuting Christians and began believing in God (he wasn't baptised though). It was said that God granted him an important victory in the battlefields. Soon around that time, Christianity became popular and many ppl converted. From then, Christianity was embedded in European history. Of course there were really bad times and good times.
During the bad times, faith became superstitions and some Christians broke off from the Catholic Church and formed their own sects. Sometimes, countries broke away from the Church (England and the Eastern World). But no matter what it was, the Catholic Church and some main denominations survived too (Cause Jesus promised that the gates of Hell will not prevailed against the church. etc etc.) btw this is my own summraised form, any expression error is just on my part, go grab an objective history of Church book and read. Interesting parts are from 300-500 AD and 1400-2000++ AD.

Though, I am a Catholic, I am not going to judge which church is right or wrong. The charismatic way of prayer is just a way of prayer. Just like meditation with the Bible is a way of prayer. There is nothing wrong praying in tongues.
Theologically speaking, praying in tongues is allowing the Holy Spirit to help you pray better as you do not know what and how to pray best. Sure, anyone will be freaked out the first time they see a mass of ppl praying in tongues. I was freaked out too but after I understand that those ppl praying are not nuts who are possessed I feel a bit better.
The thing is this praying in tongues is not a fashionable thing. It is a private gift ie u and God's link of communication. In a community, you pray together with ppl who usually have tongues or ppl who understand tongues. IMHO, inviting ppl to this praying of tongues is not a good way to let others experience God. It simply a freak show to them. Go show them God's wonderous creations, like chio bus and yan daos in church or something lah. There are 1 million and 1 other ways to do it
