Conspiracy theories annoy me

I get annoyed by these conspiracy theories because mostly they are all stupid. For example, Avril Lavigne, the theory is that today's Avril is not quite real, it's a double. What's stupid about it? That her voice and birthmarks changed. How stupid is that? Okay. Voices and appearances change a bit over 5 years, like everyone else, why don't they understand this? Or birthmarks sometimes disappear too, speaking from my own experience. Or for example, they say "she said in 2002 that she would never wear skirts but started wearing them at concerts" oh God! I won't be surprised if there are people who disagree with me. There are a lot of stupid people too.
