A few different things:
1) You've asserted that you believe "catholics are converting most of all christians, to Islam." I encourage you to read my post #33 on page 3.
Thanks. Like you said though in the post, the list of countries are strictly European and Western so there is a bias. Not only that, but their sample size taken (480 out of 70,000) is suggesting muslims were 0.6% of the European and American population, when it is actually 10 times that on average in Europe and 4 times in America and Australia. So it's already flawed.
I see also more than just a bias though, because the study was addressing the number of conversions out of catholicism to whatever denominations, not the number of christians converting to Islam and how many of those christians were catholics.
2) You've stated "churches are registered as profitable organizations." I'm not aware of this being true. Those churches for which I am aware of their status are registered a non-profit organizations.
Catholic was primarily land and money, so much so that they established the separate state of the vatican just to maintain their autonomy and their funds away from any european turmoil, with swiss guards (and bankers

)) helping out. Yes, maybe the English and Lutheran churches were based in the beginning on reasons other than immediate profit and domination, but I was speaking today in terms of the churches as organizations: They are established in the United States as tax-exempt institutions, with non-profit offshoot foundations that support charities, but primarily earn and maintain positive income:

Church Budgets and Income
Current research data on churches

As a church deacon and ministry executive, I understand the challenge and the faith that goes into projecting income and planning expenses for a church. Since the majority of churches will be preparing next year's budget in the fall,
Your Church offers this study data on church finances. Find out how your own congregation compares.
Sources of Income
The typical church counts on tithes and offerings for 93 percent of its budget. Investments (2%), revenue from programs and ministries (1%), and other sources (3%) account for the remainder of a typical church's income. Churches with budgets greater than $500,000 depend less on tithes and offerings (87% of income) than the average church, and more on revenue from programs and ministries (5%) and other sources (6%).

3) You also claim, "Organized religion is nothing more than organizations wanting to profit out of people's natural need and desire to reach God." The reality is that there are many forms of organized religion and probably as many reasons for it as their are forms.
I understand what you mean but I hold on to my position. Churches by design claim to be "agents" of God and wish to stand in between the people and the creator, and are run as a business with money flowing in needing to be more than money flowing out. Some are outrageous in demanding 10 or 20% out of their member's income as a tithe, some are more subtle and civilized in that they ask for or encourage donations, but they all run on that basis of budgets and income, and would point it out in sermons if the collection plate come back kind of light. Just because the church pastor asks for "donations" in the service, does not mean that the money are all going to charities. They go into the church funds, and these funds need to be in the black.
