That list falls way short of 30000. Also you have fundamentalists listed as one group, which actually includes many of those you listed seperately.
Prebyterian of Scotland, Presbyterian USA are the same denomination. Aglican, Episcopalian, and some others are the same denomination.
Baptists, regarless of what name you want to add to it are basically the same denomination.
Congregational and Methodist differ only in customs.
Shall I continue? Your knowledge of Protestant Churches is lacking.
I don't know where you got your descriptions but Pentacostal Churches are far from small. Some of the largest churches in Texas are Pentacostal. Four Square, Assembly of God, Vineyard, and etc. all fall under the heading "charismatic".
Gay Denominations? There is only one, the Universal Fellowship of Metropolitan Community Churches found by Troy Perry in Los Angeles in 1968. It now has 44000 members in 1200 congregations worldwide.
The Catholic Church by your own admission has "denominations" with different customs, the vast majority of the denominations you listed differ only by "customs".
If the Catholic Church was the last church on this earth I would avoid it like the plague. The Catholic Church denies the finished work of Christ on the cross by teaching purgatory; the Catholic Church mocks God with images; the Catholic Church mocks God with the Marian doctrines. None of your traditions come from the apostles and are therefore the "traditions of men".
Reformers in different countries taught God's truth and denominations were established based on their teachings. With few exceptions the reformers were in agreement on basic doctrine and Biblical truth and differed only in church government.
Instead of defending a church in apostasy why don't you come home to God's truth and seperate yourself from the Catholic Church?
