That's..not what that is..

so I shouldn't trust what you just said? meaning I should trust people on the internet

Including them and what they just told you.

But then you shouldn't trust people, including her, which means you can trust people which leads to listening to her, but then you shouldn't trust people on the Internet even what she says but then you shouldn't trust what she says and thus you can trust what others say...

Sounds reasonable enough, but I don't trust you..
