This forum needs a code of conduct. We need to be civil and productive. But I think a blog post should have more freedom. If the author made an ignorant choice of phrase, then a comment about it would be appropriate. But choice of dark/crass humor should not be reprimanded. I don't want to be posh and well mannered in my own home. No masks; let me be as disgusting and pathetic as I can be.
The large majority of humans adapt our language to the context and the audience every time we open our mouths or put our hands on the keyboard. I’d like the author to do a little more of that.
