What’s the difference between a fully automatic rifle and a semi-automatic rifle with a bump stock?
Nothing.
I believe I did mention bump stocks in my post above.
Again I agree for basically all intents and purposes, they are the same. But technically they are two different things.
Here is a good video that shows the difference between the two

Therefore the terminology doesn’t matter.
The terminology does matter. Semi-auto weapons and fully-auto weapons are two different things. If we are going to decide what guns to ban and what not, we’d better understand these things. Also the other side uses the fact that the pro gun control people don’t understand these things as way to argue against them.
