You could have put some disclaimers signaling that you understand Hitchens might not agree with this 100%, but it needs to be said anyway even if it offends some people. Hitch never sugar-coated anything, so I'm guessing being blunt at his funeral -- with properly signaled self awareness about the fact that you are being blunt and taking exception to funeral norms -- would actually be okay by most of his fans. The fact that you just put the link and made it sound like he would have wanted the reader to agree with this article, actually was a bit offensive.
Having been diagnosed with cancer last year, writer Christopher Hitchens has died. He was known as as an outspoken atheist, which is not, in itself, identical to being a committed rationalist in any systematic way. Even so, he seemed to have the virtue of moral courage, the willingness to speak the truth as he saw it, without fear.
