Better. That actually supports the assertion that Russia does engage in left-targeted disinformation (in Canada, on Twitter.)
It also supports the original point you dismissed as “wrong” – of the 90 “most influential” accounts, only 9 were subjectively identified as “Canadian far left”.
Maybe you should spend more time reading the actual articles, and not just their headlines?
