To be honest, I don't belittle the commentator (assuming you mean the CPUSA). They belittle themselves. You might have had more of a case to 'be afraid' of them back in the 1970s or even 1980s. Back then, there was still a USSR backing them. Right now they are the moral equivalent of a guy on a soapbox yelling at passers-by at the Town Square. Their message is old, outdated, repudiated even by those who tried to force it on other countries. When your list of True Believer clients is basically down to North Korea and Cub (make no mistake, Vietnam and China are way different) it says something.
