Let them build their Damn Nigerian church someplace more appropriate, like NigeriaOK, how about if the United Gypsy Clans of America wanted to take a property in Crofton and declare they were setting up a Meditation Garden for 100 people--except 500 people showed up every weekend for rowdy picnics?
This Nigerian "church" is a band of people focused on acquiring money and wealth by warping gospel messages from the Bible. Their church leader just purchased a Gulfstream V personal jet to show his piety.
It is a Ponzi Scheme tricked-out with religious gobblydigook. Once they mark-out 299 parking spaces, they will cry racism when residents complain about the 1000 people showing up in their completed 64,000 sq. foot complex after parking on nearby residential streets. Then limited police and fire resources will have to be set aside to manage this once-a-week religious "festivus" to force compliance with approved capacity. Following that will be a blizzard of discrimination lawsuits stripping local coffers of money that could be better used for education of infrastructure.
It's OK to say no. Incentivize groups like this to develop their cult camps out where they won't bother anybody.
