For me, it's the very common belief that domestic violence victims are "enablers" or "co-dependent" and that a "normal" victim would just leave. The depths of ignorance embedded in this view make me feel both frustrated and angry.

That the moon landing was real. As if.

In general, I think that America's views on sex are puritanical and insane. We are way, way too strict with statutory rape laws. Don't even get me started on the illegality of prostitution.

I find offensive the notion that people "others" who are not just like us do not have the same needs, desires, worth and rights as "us".

I really wish people would recognize that tacos have souls.

Is it guacamole?

What mightshould said.

Also what mightshould said.

That men and women are "hard-wired" to be different.

the contempt for book-larnin'

Yeah, basically what mightshould said. Exceptionalism of any variety gets my hackles raised instantly.

The belief that luck is the hand of God.

Opinion = fact.

Also that all opinions are equal. They are not. An informed opinion holds more weight than an uninformed opinion.

That consciousness is an epiphenomenon of matter.

The belief that the offense of one individual or group requires action from everyone else to correct that offense.

For example, the word 'handicapped'. I cannot see the offense that many handicapped people find in that word.

This is, of course, a privilege of being privileged.

The belief that financial or career success equals intelligence and hard work.
Looking up to billionaires and taking their advice as if they are brilliant and can be emulated instead of knowing that their circumstances are due in large part to luck and timing and are not repeatable.

Also relatedly, the belief that people who excel at one thing should have sway in other areas. Financiers are not necessarily good politicians. Actors' opinions about medicine should not be influential. I don't think many people would readily admit to believing this or those particular examples, but I do think a lot of people succumb to what I call "the fallacy of being smart."
I'm one of them. I generally consider myself smart and I do know a lot about a few things, but I rarely take expert opinions at face value as if I could somehow do the research better myself. Not the case.
