Excellent article. Can't really fault it. Another example of the WTBTS arbitrary rules. In reality most JWs actually get round the limitations by having " present days " & lavish anniversary parties. ( There are also a surprising number of JWs who have a meal on their birthdays as well , albeit they keep quiet about it. )
Perhaps you could add to your list of events or concepts in the bible regarded as negative that the WTBTS puts a positive spin on is the generation. The WTBTS admits this ( reference below ), yet they now interpret the generation as the "anointed".

Previously, this journal has explained that in the first century, “this generation” mentioned at Matthew 24:34 meant “the contemporaneous generation of unbelieving Jews.” That explanation seemed reasonable because all other recorded uses that Jesus made of the term “generation” had a negative connotation, and in most cases, Jesus used a negative adjective, such as “wicked,” to describe the generation.
