So you admit to being an extremist then. You probably find problems with a great deal of the modern world as well.
You can't buy things online with cash. Your opinion on what people do online is therefore, colored significantly and is definitely out of touch with most people's experiences.
Declaring anyone who disagrees with you (and acts on those ideas) as an extremist is a neat trick, but the only thing it actually gives you is an ad hominem.
