So what?
Are you trying to discredit the message by discrediting the messenger?
Is every non-Catholic wrong by default in your book?
If there is something wrong with the content of the article, how about you address that instead of disparaging or trying to slander, the author?
I'll bet that person didn't even bother to read the OP article in full! Pretty sad when one imagines they get to tell everyone what they can or cannot read rather than ACTUALLY reading what the author said and addressing it intellectually. What laziness!
