Honestly, I think it could hurt somebody's feelings. I get a bit tired of reading about people's pets and I'm sure some get a bit sick of reading about my extraordinary nieces and nephew or my high risk job but hey - they friended me and I friended them. You skim over the stuff that bores or annoys you and move on.
POD. You can also "hide" people if you find them to be serial updaters who bombard your feed with annoying updates. I've done this to several people although sometimes the sheer ridiculousness of some people's status' can make me howl with laughter.
For the run of the mill awareness updates, I agree with you both. We all have our little Facebook quirks. But I think the OP is referring to a specific strain of them going around which a pp posted upthread. I'll repaste it here (kind of ironic as I wouldn't do it on Facebook, lol

. I'm adding bold/red to the part I think is problematic:
"Put ♥ this ♥ on ♥ your ♥ status ♥ if ♥ you ♥ know ♥ someone ♥ who ♥ has ♥ or ♥ had ♥ cancer! ♥ All I wish for in 2010 is a CURE! ♥ Dear God, I pray for the cure of cancer. Amen. ♥
93% WON'T Copy and Paste this, will YOU 4 just one hour?!"Up until the problematic part, it's no better or worse than any other awareness status update. But the trying to compel people into posting it into their status by made up statistics which imply that the alleged 7% who post somehow care more about those with cancer is where it crosses the line into rude and obnoxious IMO. And though I've chosen not to respond to the rudeness and obnoxiousness at all when I've seen this among my friends, I can see why people might choose to respond to it. And criticizing it doesn't make it rude. I ignored it the first few times it popped up, but this seems to be spreading like some kind of wildfire. Now, there's a variation of the autism variation where people are praying for acceptance of people with autism vs. a cure. As well as the pregnancy/infant loss one with the controversial issue statement at the end.
Now, if I were to go with my gut instinct and say on my status it's a stupid and obnoxious thing to post, that would be responding to rudeness with rudeness. So I didn't post that. I liked the OP's original post because it was a bit snarky, but not rude.
I've seen at least 2 people on my friends list express their annoyance with it. One didn't specify she was venting about this specific variation and inadvertently offended a friend who had sent a prayer request to her for specific individuals he knows. They patched things up once each realized the miscommunication.
Another posted the hearts with a joking comment about posting it if you know people you want to hit. But it was obvious what she was making fun of and that's she's kidding about the violence part, so she's getting favorable comments on it.
