Nobody said anything about giving peadophiles rights.
The premise on which we live as a society is that EVERYBODY gets equal rights and opportunities untill proven guilty pf an offence.
The OP asks the following question: can you put someone in jail because you do not agree with their views?
Let me remind you that (appart if you are a suspected muslim terrorist, but that is another debate) in this country, you can not be emprisonned because of what you think.
Thank God!
Of course I want to cut the balls off these bastards, but so does the parents who lost a child to a drunk driver, the person who lost a relative to a negligent doctor, etc....
Where does it stop?
This is democracy. Look at what is going on in the world around you. It is definitely not the ideal system, but it is much better than anything else.
If you can think of something else?
