'Entitled to your opinion" that's the best legal defense I have ever heard, be sure to use that with a judge!
It is not opinion on what the law says and what is and is not illegal. Yes there is interpretation of the law about situations like if X qualifies as self defense or murder, but there is no opinion on if murder is illegal or not.
My opinion is that the practices and greed of the MPA, music recording studios, and corporate media conglomerates only fuels the quantity and appeal of piracy. Not to mention companies like Adobe that want to force you to pay a subscription to use their Creative Suite products and when you stop paying they block you from even having access to your files (not to mention not being able to use the software you are paying for because their servers go down for extended periods of time).
Everything i said in the last paragraph is an opinion, what the official law says in black and white is not opinion.
