> Apps like popcorntime are similar to assault weapons

All analogies breakdown under close scrutiny.

What I don't understand is why people contiue to make analogies where none are required.

The arguement against Popcorn Time is simple and straighforward: It is overwhelming used to circumvent copywrite / avoid paying for access to content.

Whether anyone agrees with that argument or not is immaterial to my point: we don't need to compare the arguement against to anything else because its meaning is self-evident.
