Razor wire is a type of fence and barrier. But more importantly, why did the Biden administration fight in court for their right to remove razor wire from the Texas border? What does that action suggest about the attitude of the Biden administration towards people crossing the border illegally?
Sure, but I would consider mines laid in a strait a barrier or fence, and I would consider the radiation at Chernobyl a barrier to entry, and I would consider a hedgerow a barrier or fence as well. I think it's important to specify the type of barrier or fence when discussing the removal of it, it's a long gray spectrum and not black and white.
It it generally legal in the USA to put a fence around my property, but it is not generally legal to put razor wire around my property, so even the US govt thinks there's a difference.
It's important to consider the words and the portrayal of events when discussing politically charged topics.
