Title: 
A direct solution to the Generic Point Problem

Abstract: 
We provide a new proof of a recent theorem of BenYaacov, Melleray, and Tsankov. If G is a Polish group and X is a minimal, metrizable Gflow with all orbits meager, then the universal minimal flow M(G) is nonmetrizable. In particular, we show that given X as above, the universal highly proximal extension of X is nonmetrizable.
