There are plenty of .onion websites out there that allow you to use bitcoins anonymously.
To get BTC anonymously I can only buy paysafecard offline and convert into BTC. Everything else can be traced. And in this forum I've seen most threads about this kind of exchange.
Bitcoin is for both the completely anonymous and for more traditional transactions.
This forum and the freenode #bitcoin* channels are for the other side.
There is no such statement that anonymous people are not welcome here.
