Pete,
Here are the answers to your questions:

"So do you object to the sale of any of these patches ever again in the future on a for profit basis?"

Yes I do - unless the proceeds go to help those left behind (like the fours kids of one of them)

"How about people who profit from selling JFK memorabilia?"

In my opinion - no difference.

"What about those who make movies about Jack the Ripper?"

Not the same issue.

"At what point does the sale of this stuff once again become acceptable?"

IMO it never does.

Best, Mr."P"
