Based on my personal experience, being one of the few pro-nuclear voices in the ostensibly anti-nuclear social media [filter bubble], I'm half-inclined to accuse you of being an anti-nuclear shill. But I think you're not, we just live in different filter bubbles.
As for nuclear NIMBYs, sure, individually they don't have the money (I'm a nuclear YIMBY, and I don't have it either). But there's plenty of organizations with money and influence, campaigning against nuclear - e.g. fossil fuel industry, Greenpeace. So I'm going to back the GP - everyone does that.
