I don’t agree. All laws are up for interpretation. That’s why we have the judiciary. Law makers draft laws, courts decide where those laws fit into the wider body of law.
The kind of law making you’re implicitly advocating is tantamount to despotism. Drafting a law that outlaws islam might well be clear in it’s wording, but it needs to be tested against the law that allows freedom of religion, freedom from persecution, and a ton of other laws no doubt. The claritiy of language with which a ban on islam is articulated is all for nought if it’s contradicted by, and incompatible with other laws.
Although, GDPR has been explained very clearly. And we’ve been given a loooong time to digest, understand, implement, and question it. I don’t think any reasoable person can make a compelling case against GDPR. But unreasonable people can, and as we’re seeing, they will.
