@duckrocks let me provide an alternative take on this.
The Monero community is very passionate about privacy, and we all acknowledge that real privacy is incredibly hard to get right. Those of us in the Monero community even realize that Monero has several weaknesses in regards to our own privacy.
What is very frustrating is when coins with gigantic claims to fame about their "impenetrable privacy" pop up out of the wood work all the time. Projects like Verge, TokenPay, and more.
