I am not getting why anyone would find it “mean spirited” even if they object to the sentiments, but it is certainly lame. Not only is the whole conception lame (whether intended seriously or as satire), but the choice of ‘slogans’ is puzzling and inept. A couple of the slogans seem to be so general that anyone from anywhere on the political spectrum could happily endorse them. (E.g., “If you are not outraged, then you are not paying attention”. Outraged about what? Economic inequality? Taxes and Obama? The fact that gays are, or are not, allowed to marry?) Most of them seem to be things that a militant feminist or LGBTQ activist might say (or feel they ought to say) in particular circumstances, perhaps if certain “politically incorrect” things were said to them. These make little sense as stand-alone slogans or “thoughts for the month”, and are not likely to appeal to liberals or progressives across the board. Few if any of the slogans have much to do with general liberalism or progressivism. Apart from “We are the 99%,” i saw nothing that even hints at economic or class issues.
