“I think this is tacky...”
Not necessarily. Perhaps he was the type of person very, very involved in politics. I have read obituaries stating ... in lieu of flowers donate to animal rescues/environmental organizations/soup kitchens/missionary groups etc... It involved a passion that the person was involved with when they were alive. Just a thought.
Don’t get me wrong, he’s got every right to do it, but I have friends and relatives on both sides of the political spectrum, so I wouldn’t want to put some in an uncomfortable position by doing such a thing.
