The post in question, as distasteful as some may find it, is an opinion of an individual person who has the right to express it, just as everybody else has the right to criticise it out in the open. As with any open forum, of course not all posts will agree with, or represent personal opinions of management or moderators, however, this site and forum is not here to propagate the views of its management, but only to allow fair and open discussion as long as it follows some basic rules which this post does.
If every opinion one disagrees with was barred from any sort of discussion, how could you ever hope to allow people holding said opinion to see that there's an alternative view?
