American Islam is extremely wealthy, funded with billions of dollars.
Far more American Muslim money is sent overseas than is raised overseas.
The continued exemptions on offer that allow too many religious organizations to avoid transparency over their activities and finances, while benefiting from tax exemptions, federal grants and other public benefits, is a dangerous state of affairs, from which radical organizations have benefited considerably.
Greater transparency and less government foolishness remains, as always, a key line of defense against the theocratic and other totalitarian menaces that threaten Western society.
