You say semantics, I'd say precision (typos not withstanding)
With specific fields certain terms have specific meanings, if you use the term in the correct way then what you say has credibility. Use the same term incorrectly and you can be instantly dismissed as being irrelevant.
Like there is a clear difference between illegal and unlawful but most people don't recognize that, which is why the Federation Against Copyright Theft gets to call itself that instead of the more accurate Federation Against Copyright Infringement.
So the more people that use the correct terms in the correct way the better, particularly when it's a subject connected to politics or the law where it's all nuance and fine distinctions.
