Confirmation bias afforded by ignorance, willful or just plain, is a strong drug, never more so than in today's utterly polarized world where so many have consciously or subconsciously decided to judge everyone and everything based on intersectionality instead of valid logic based on factual premises and objectivity. In short, many today will see what they want to see because it fits their preconcieved biases, doing so allows them to continue to support their believed narratives, and it makes them FEEL good about themselves and their beliefs, facts and logic be damned. This is nothing new, the world has always had people who act thus way, what us new is the ability for these types to gain strength in great numbers via social media, couple that with actual media, academia, political, and lately economic/business entities desire to gain clout and/or resist being demonized by the hoard of the unthinking and actually adding validity to such nonsense, well, we end up with what we have today.
