Definitely not on copyright grounds, since almost all state flags (except Georgia, Mississippi, and soon to be Utah) are old enough to have entered the public domain.

when there’s not a recognised disability involved but just health issue/s (which could be “disabling”).

From the Equal Employment Opportunity Commission, in regards to the ADA:

Under the ADA , you have a disability if you have a physical or mental impairment that substantially limits a major life activity.

Essentially, if you are disabled, you have a disability, whether recognized or not. If you are not disabled, then you do not have a disability.

Under this definition, something like asthma, which is fairly common, can be a disability when it comes to strenuous activities, but isn’t something that is immediately obvious to someone just passing on the street.

As far as it being ablist to assume that someone not showing signs of disability isn’t disabled? No, that’s silly. Not believing them if they tell you they can’t run a mile because they have asthma? Still no, that’s skepticism.

Ablism would be something like planning a company outing, and choosing the location up a tall, steep hill when other options were available, specifically because you don’t like the fact that your coworker has asthma.

It’s not.

“Hey, look at that girl/car/tree/Chihuahua” isn’t a left nod. It’s eye contact, then you look at the thing.

“Come here/go there, let’s talk” isn’t a right nod. It’s a weird neck movement where your head is kind of sideways and you’re nodding in the direction of the place you want them to go. You usually use “Hey, look at that tree” first before you try to get them to go to the tree to talk.

Can confirm up and down are correct enough, though. Up is for people you know, down is for people you don’t.

Go for it anyway. If this girl is so shallow to reject someone for something stupid like that, she’s not worth it and Anon dodged a bullet.

The dude could probably take out your lungs and heart with his eyes closed.

To be fair, so could I.

“Sunwise”, and for the exact same reason.

Clocks go clockwise because their predecessors did. What were their predecessors?

Sundials.

How does the shadow go around a sundial? Well, sunwise, of course.

Counterclockwise, as said in another comment, was “widdershins”, from a Middle Low German phrase meaning “against the way”.
