It isn’t strange to use your non-dominant hand for things, no. Maybe most people do lean toward using their dominant hand for everyday tasks, but I think it’s a matter of habit for most things. “Non-dominant” doesn’t mean “nearly useless”.
I would say it is a bit strange for your friends to pay a lot of attention to which hand you use to unlock doors.
I don’t think the usual portrayal of the issue is that animals can exploit any other animal that is less intelligent; it’s more like, there’s a minimum level of intelligence or consciousness for human rights. You might call it a cutoff. Which could be seen as a contrivance to give humans the right to exploit other animals, but the problem with dismissing this view as self-serving is that the logic cuts both ways. Humans are the only animal that is expected to care about morality in the first place; nobody is getting mad at cheetahs for eating ostriches. So it’s hard to argue that there is no cutoff relating to morality at humans, the question is exactly what that cutoff entails.
Not sure about India, but NASA has used GoPros on Moon-related stuff. Artemis I had 4 GoPros on the ends of its solar panels when it orbited the Moon last year.
This all sounds extremely familiar. Owning the libs as a show for their base of support back home.
