I wouldn't personally do what Brenda did, I vowed never to enter a kh again after the
last time I went, and I never will. Brenda hasn't been to a hall for over 20 years, so it's
doubtful if any jws knew her anyway. They would probably have thought she is a born
again Christian who would have partaken in line with their beliefs.
As for being disrespectful to jw beliefs, when are they respectful to any non-jw's beliefs?
They regard any other religion apart from theirs as false anyway, and said so specifically
in kn37, as well as in much of their literature over the years. As purps said, we were all
lied to by the watchtower while we were jws, so if someone decides to go to their annual
ceremony to reject Jesus' sacrifice and have a little fun at the jws expense while they are
there, then good for them.
