Ok the safety issue wasn't thought out, there's probably some saftey issue with selling home made food and beverages in some bureaucratic refulation somewhere, probably real chance of health is probably next to zero.
but, the law is the law, just because they're kids doesn't mean the law is waived for them. Also you quoted me on the statement
What if 3 black men were selling lemonade without permits, will you feel differently then?
But you didn't answer it, if it was 3 black men selling lemondae on their front laws, nobody would give a damn.
In order for law to be just and fair it has to apply for everyone.
Also, In most countries you cannot turn your home into business property by the way, you have to pay business rates.
Dude, let it go.
