I feel like the least I can do to respect the memories of those murdered is to, as Speier suggests, banish "drink the koolaid" from my lexicon. Used far too much in tech culture and simply isn't necessary.
More than one way to skin a cat has more jokey roots, that it's a shame haven't survived, becoming just the bland intro we now use without the punchline.
I also think the term has taken on a bigger meaning since then, retroactively incorporating the merry pranksters lore. You really don't know what's in the kool aid, and whether it will be good or bad. That's what makes the phrase so versatile.
Don't take death so seriously.
