  The frequently discussed strongly interacting gauge theory with a fermion
flavor doublet in the two-index symmetric (sextet) representation of the SU(3)
color gauge group is investigated \cite{Fodor:2012ty}. The chiral condensate
and the mass spectrum are consistent with chiral symmetry breaking at vanishing
fermion mass. In contrast, sextet fermion mass deformations of spectral
properties are not consistent with leading conformal scaling behavior near the
critical surface of a conformal theory. A recent paper \cite{DeGrand:2012yq}
which could not resolve the conformal fixed point of the gauge coupling from
the slowly walking scenario of a very small nearly vanishing \beta -function is
not in conflict with chiral symmetry breaking reported here. A light Higgs
impostor could emerge as the dilaton from spontaneous symmetry breaking of
scale invariance or, without the dilaton mechanism, as a composite state.
