My responses are directly to the comments they were in response to. So that comment was in response to:

> So only a few types of mail generate a loss, and it is a loss of $1.7B, and advertising mail generates a profit of $5.7B, yet as a whole USPS operates at a loss of $8.5B. This doesn't leave me with much faith in their self-assessment of the profitability of specific types of mail.

Because you switched from 'is X subsidized' to 'well...if X is profitable, it must be because they cannot perform accurate accounting'.

They are both profitable categories of mail and neither are 'subsidized'. The 'subsidized categories' are those that are losing money.
