You-the-reader have the right to read anything you want.  I can’t stop you; furthermore, I don’t want to stop you, and I think it would be morally wrong to try and stop you.  And that includes reading stuff I don’t like, by people I don’t like, saying things I don’t like.

You likewise have the right to not read anything you don’t want to, and I have no moral right to make you read anything.  No matter how worthy and important and good for your soul I may consider it to be.

You also have the right to say whatever you please about whatever it is that you’ve read, and I have no moral right to stop you.

But.

If you’re going to make public pronouncements on the quality or value of a work, and you’re planning to say anything more than, “I do not intend to read this book because I disapprove of the author and disagree with his/her views” . . . then you have a moral obligation to read the damned book before you say anything.
