All your examples are completely bogus.
Those examples are the reason for residential zoning laws.
Clearly this ordinance is a double standard. If a Boy Scout or Monday Night Football can have a weekly event and meet in a house certainly a invited guests can meet for worship.
Private property rights are exactly that, for use on your private property. A homeless shelter, truck stop, outdoor bazaar, toxic waste disposal site, sex club fall under "public" property use where the "public" need access.
And what about signs for “ Sarah’s graduation party” “Bill’s Superduper Bratwurst cookout?” Our neighbors have a baptismal service in their backyard pool a couple times each summer. It is followed by hymns and singing, and, of course, a potluck. Good fences make good neighbors. I can not imagine anyone complaining about it.
