I think the point is that these articles don't prove anything of the kind. The first one "examines the ways in which Cultural Marxism has moved from the ‘fringe’ to the ‘mainstream’", paying "particular attention to the localised use of the conspiracy in the ‘Safe Schools’ controversy of 2016–2017, whereby Cultural Marxist tropes were imbued with local concerns about sexuality and gender issues". The second one "argues that “Cultural Marxism” is an antisemitic conspiracy theory", focusing "on three of the main proponents", and shows that it "misrepresents the Frankfurt School’s ideas and influence", the latter not being obvious from a quick reading.
