What makes Shapiro "alt-right" and not just a traditional conservative?
I think he is a regular conservative who toes the GOP line more than anything else.
His book is a good guide to both his beliefs, and as I later learnt, the beliefs of old people who watch Fox News:
1. WMDs were real and were hidden in Syria and Iran; Obama suppressed the publication of this knowledge.
2. Black Lives Matter are thugs who pay protesters - his book goes further and suggests back communities pay kids to get shot by cops.
3. Cruz as the ideal principled conservative, Trump as the dirty effective leader.
4. Universal healthcare is slavery for doctors.
5. Islam is an existential threat.
6. Obama deliberately allowed terrorists and others to enter through the Mexican border.
7. Transgender people should be referred to only by their sex at birth; it is a delusion.
8. Gay marriage is wrong
9. Climate change is a left-wing conspiracy.
10. Universities promote the homosexual agenda; homosexuality is a sin.
He was an editor at Breitbart, which had a separate section called "black crime" while he was around (and is notoriously slanted and short on facts in general), and there are a few tweets showing his racism towards Arabs. Both point to alt-right beliefs. However, he personally got oven memes on twitter and fired back, so his background stops him from truly becoming accepted as one of them.
I think he's a gateway to people like Molyneux, he's personally a more openly racist version of the mainstream GOP.
Edit - to be clear, because of the 9th point alone, the death tolls from mainstream conservatism, the alt-right, and Ben Shapiro's utopia will all be very comparable and in the hundreds of millions. So it is useful to classify them if we're trying to fight them, but in terms of the harm they do, they are close to each other.
