I think once Donald Trump gets into office he's going to rethink everything he said or plans to do. He wouldn't dare touch marriage equality, and he wouldn't dare touch gender equality. I can see him saying something stupid and starting a war though.
Also, that wall isn't going to be built (but let's not pretend illegal immigration IS NOT an issue), and even if he does, there is always an exploit of getting across the border. It would also be impossible to deport all the immigrants. Immigrants do most of the work, after all.
He uses people's anger and frustrations and promisses stupid shit in order to make conservatives riled up. Now he's won his game, and doesn't know what to do with his prize.
The only thing that absolutely bothers me is how dangerously close he is to fucking up the first amendment. I understand flag burning is scummy, I understand even Hillary wanted to make it illegal, but it's still freedom of expression... Then again how's he gonna do that with people watching him? Same with everything else. then again there is rebublicans everywhere in office so perhaps maybe this is all achievable
