There are five possibilities:
- Trump was given this as proof that the guy is really a gang member, didn't ask if it was fake, presented it without vetting it
- Trump ordered someone to find proof that he's in a gang and someone gave it to him as proof
- Trump ordered someone to create proof that he's in a gang
- Trump was given this as proof, he asked if it was fake, and was told the truth, and presented it anyway
- Trump was given this as proof, asked if it was fake, was lied to, and presented it
All of these have problems.
Ease of use shouldn't be confused with ease of setup.
I use discord every day but I am not a gamer so my use case is different.
Schools had to set up classes quickly and use a platform that provided the least amount of friction for students. They likely figured out most kids were familiar with discord over zoom.
I never heard of schools using Discord but it doesn't sound like a good idea. And again, I say this as someone who likes Discord. Using an app that's primarily for gamers and adding school to it sounds like a recipe for disaster.
