You raise good points, and I think there are actually at least two phenomena here:

1. The liars: people cynically playing up fears of "losing democracy" as a political tactic to support some other political programs. I think this is especially obvious from candidates, activists, political operatives, etc. -- people sophisticated enough and engaged enough to know and think about what they're doing in a serious way.

2. The un-serious people: those you describe. Basically irrational people who believe a jumble of things without exercising the ability to prioritize or disengage the contradictions.

I don't think the boundaries between these phenomena are hard ones (e.g. you can often push un-serious people into liar territory by challenging them to prioritize).
