This is a Bitcoin forum, not a fiat forum. If someone is being mislead by prices being given in Bitcoin, or feels mislead by it, should not call himself a bitcoin enthusiast and either educate himself so that he no longer feels mislead, or look for another hobby.
What you said is true and it was already said by the people you quoted hundreds of time, so don't think that they aren't aware of this.
You didn't pay attention about the main reason why this topic was created. In fact theymos called for it essentially for external investors who don't have forum accounts and who may deal with other coins in addition to BTC, that's why an email was added for example.
