"lying"? WTF do you mean by that?
While I can appreciate many styles of musicianship and their varied genres of musical backgrounds, I'll admit (and have often) that I'm a snob when it comes to musicians who don't have RESPECT for "the Blues".
It is one thing to not have "the Blues" as a formative musical background, but then it's something totally different to not respect the very genre of music that was the precursor to the genres of music that WERE. Both "Rock & Roll" and "Folk" (as in late '50's/early 60's style of "Folk" which was an amalgamation of "Bluegrass" & "The Blues") are direct descendants of "BLUES".
