My point is that they don't really give a shit. I'm not saying that's a bad thing per-se, there's only so much a human being can genuinely care about and devote effort to after all, but such actions are shallow to the point of being somewhat insulting.
I feel the same way. Another example is when someone famous dies and various internet forums get flooded with "RIP" comments that mean absolutely nothing to anyone other than the poster saying "Look at me, I'm also part of this!"
