Wikipedia is great for information. Billions of facts and data stored on there for easy access.
The problem is that most people don’t understand a bit of it. They just quote an excerpt, talk some illogical bullshit and hoping that someone of the same low intelligence as them will accept it. It’s difficult as heck for any moderately intelligent person to read, since the excerpt most likely isn’t even related to said topic. Only relevance is a keyword. That contradicts everything.
People need to take the initiative to develop logic, but hell, with the advent of Wikipedia and copy&paste, they’re not going to think anymore. As long as the article on “logic” exists, they are safe.
