The ideological principles and principles on which these organizations operate can constitute an attractive factor for society, and thus these organizations will be community leaders.
I reformulated the question reading -- "Can civil society organizations form community leaders?"
It all really depends on the form of society one lives in. I would argue that civil society or civil association institutions (as labeled by Tocqueville) are a product of the Anglo-American legal culture and have issues working well outside them--especially in one shaped by civil law models.
And one where leaders emerge from below and not through the selection of state-controlled institutions--then yes, the institutions of civil society (voluntary school clubs, local and school youth sports teams, voluntary community action things, local youth groups like the scouts, etc will shape future leaders. But this presupposed a society where the association and organizations are locally launched and not a product of state bodies (here in Anglo-American tradition schools were locally controlled and not strictly controlled and a product of state making).
The very feasibility of forming civil associations that are independent of state control or funding requires private beneficence and the legal form of the "Trust" to ensure funds are secured and directed for long-term use. If associations and organizations are economically state-dependant they will not really be what Tocqueville et al would understand as true civil society. Here what much of what Continental Europeans think of as being civil society institutions are in fact state dependant ones (either directly or indirectly) and what they understand to be civil society is, in reality, ersatz civil society.
Yes, I agree with you, but do you agree with me that society and its conditions are what separates its needs from such institutions, for example: Is there a need for these institutions in countries such as the Arab Gulf, based on diwaniyas, which they consider sufficient for this purpose?
What you call "diwaniya" is similar to a court/drawing room for the feudal aristocratic manor/palace, and while it is a place where one deals with issues of public action or business, it is not structurally a thing on its own, but part of the household/estate. Thus the "diwaniya" is too much a part of the patrimonial household order, more tied to customary-traditional rule than a legal-rationalistic rule (per Weber). So the short answer is "no".
To understand why that is the answer you need to understand that the institutions of civil associations have an autonomy and independence from those who form it (that while it is created by private persons, it is no longer strictly their property [see English law concept of a "trust"]); like a corporate body framed through a trust to give it means to do what it is set up to do. The issue here is that without such bodies being possible it would be rather very very difficult to form the basis of the high trust, legal-rationalistic based system of network formations (see Weber's Economy and Society and Durkheim's The Division of Labour in Society; I would also recommend Ernest Gellner's The Conditions of Liberty, pages 44-52).
In some cases, the formation of CSO initiated by community leaders, in Indonesian context, the role of local leaders could be very strategic in induce changes and social transformation. Therefore, some social policy interventions often involved local leaders
