No, it is not sensible to "conclude that both of those positions are by and large rhetorical shams". An age old seeming inevitability is that longstanding gripes get their banner taken up by charlatans dishonestly using them for personal gain. This does not mean the original concerns are dishonest or invalid. Rather it means we need to scrutinize people referencing these topics to see what they actually do when they have power, rather than uncritically supporting them merely because they claim to care about something we do.
