If they can’t explain their opinion in their own words is it really their opinion?
I don’t think “can’t” is the right assessment here. Less unable and more unwilling.
If a piece of content expresses what I’m trying to say, why use additional effort to reinterpret it into my own phrasing. We’ve all only got so much time+energy, it seems like an unnecessary waste.
At the same time, like OP said, this is a pretty lazy method of communication and thats not always suitable. It also leaves more ambitiguity; just because I interpret a piece of content one way doesn’t mean everyone will.
Sending people memes isn’t the best method of getting your point across, but it does have its place. Especially when time/energy is limited.
