What we have is a future president (ugh...) who has repeatedly shown himself to change his mind at the drop of a hat, be easily engaged and enraged on social media, and who has a long career (since long before he even considered running or POTUS in the 90s) of racism and misogyny (not to mention admitting to and taking pride in sexual assault...).
The fact that we DON'T know what he truly intends to do is terrifying, and that is why people discuss it. We know what he has said he intends to do .We know that some stuff he has backpedaled on, only to come back a few days later. That is exactly why people feel a need to discuss it.
And we also know that his vice president and growing cabinet are much more consistently "on message".
