But it's not about not getting the sarcasm. It's about not bothering to read the actual post and commenting based on the title alone.
I did read the post, and I disagreed with the assessment of the title itself given the post content.
Again, the nature of "sarcasm" wasn't clearly inferred by the OP.
Moral of the Story - If you want to clearly communicate, then clearly communicate. Else, don't blame others for how the message is received.
