You seem to be implying that any gathering has the exact same odds of being a super-spread event regardless of personal responsibility and precautions. That's not how this works...
Neither the peacful capitol protest or the thousand days of violent riots in Portland lead to significant upticks in corona virus spreading, but some spreading did happen.
Reality's supposed liberal bias is an illusion, concocted by a decentralized network of activists who have quietly infiltrated all of our institutions and suppress right leaning opinions with what amounts to bullying. Don't believe me? Try editing any remotely political article on wikipedia with anything but the "approved" narrative carried by lefwting sources with a suspicious consistency.
There is more than enough uncertainty in the reporting of contemporary events for news agencies to disagree while remaining factual; yet, suspiciously, the set of "reliable" sources are nearly always consistent in their interpretation of events and the language they choose to slyly inject political bias into their articles.
Objective journalism is dead, and was long ago replaced by increasingly naked political activism. Sure, it's impossible to be truly objective, but that's not an excuse to constantly manufacture one sided propaganda. Apparently people are so hung up on diversity of skin color/gender/sexuality that they've lost sight of the entire point, diversity of thought.
