Not sure what you're asking. Why do people hate conspiracies? Or, why do people hate conspiracy theories?
I think you mean the latter rather than the former. Anyway, I think it's because most conspiracy theories tend to be very complex and convoluted. If
group A is involved, then groups B, C and D must be as well by association. Most people can't think like that and quite frankly, find it ridiculous
to even try.
