Alt-right is just a meaningless catch-all term to describe someone who is sarcastic and "not-liberal."

Unfortunately, this isn't true. There definitely is movement afoot on the right side of the spectrum that distinguishes itself from the standard U.S. "conservative" camp of roughly the mid-1960s to present in many disturbing ways (open and enthusiastic embrace of race-baiting techniques, climate change denialism, and an abdiding belief that political correctness is basically the greatest threat that humanity has ever faced) that many traditional conservatives actually find quite ridiculous and/or outright repugnant.

The WP entry may not be the best, but for further research here are two fairly cogent descriptions you may consult, from two (otherwise, in a normal world) diametrically opposed sources -- NPR and Glenn Beck.

Like Beck says, while Trump supporters generally cannot be fairly categorized as alt-right, "they are being influenced without knowing it."
