Well, if noone cares, then your issue maybe just isn't that important.
I don't think that's the case, but we have to account for the possibility that your priorities just aren't particularly good priorities that other people care about.
I say I don't think that's the case because plenty of people do care about some of this stuff at least to some degree, or at least agree with it when asked.
People tend to be very down on the system or on politicians or on the ability or willingness to do anything in the common interest, and that's mostly part of the liberal lie as well. There's plenty to be done and plenty of people willing to do it. Those people need the power to do it, though. Sure, getting those people to where they need to be is hard, particularly with leftie types who will immediately get discouraged the moment their politicians aren't paragons of justice with a magic wand to fix every issue, but that's not the same as saying nobody cares.
I'd much rather have people get motivated than discouraged, and I don't need to win every fight, especially not right away. It'd rather move in the right direction than pout about it, even if the short term practical outcome is the same.
