There is no uproar about government taking away automatic weapons, as producing new automatic weapons has been outlawed since the 70s. To purchase one, you have to live in a state where it is legal to own, find someone owning a pre-ban automatic rifle and who is willing to sell, do some ATF paperwork, pay some fees, wait some time, and then you can get it. However, given how rare those guns are, we are talking prices around $20k+ (mentioned elsewhere in the thread, I personally have no idea about the actual prices as I have never been interested enough to look into it).

The only uproar about “taking them” that I have heard in the past decade was about taking away guns in general.

No. Any uproar is over attempting to ban semi-automatic weapons. The fact that you don't understand this fundamental difference should be a big hint that you shouldn't be arguing about it.
