All people do in reality ... if for some reason you choose to disregard the huge number of fairly autonomous communities on Reddit?
If I used that ultra-broad brush for HN, I'd say that all commenters here seem to do is post links to xkcd 927 and the wiki page for ad-hom.
If Reddit was more like, say, StackExchange, or Wordpress.com, or Discourse—a hosting site for "communities" which happened to use the "Reddit engine"—then it wouldn't have nearly the PR problem it has now. Nobody blames Wordpress.com for the content of somebody's blog hosted there.
There is a reason WordPress has the .com/.org split, and it's not just that large customers demand to self-host. That could have resulted in something more like GitHub Enterprise, but instead you see a well-supported FOSS offering. Why? Because this split allows WordPress.com to maintain a very strict TOS that disallows many types of content, while still allowing other people who don't want to adhere to those policies to "run on WordPress" easily by using the WordPress.org software either directly or through third-party hosts.
If Reddit was smart, the "Reddit engine" would be a well-supported, easy to install FOSS offering like WordPress.org, and there would be a healthy ecosystem of third-party hosts running that software. Voat would just be "Yet Another Reddit-as-Service Provider", instead of a competitor and political statement.
As it is, the Reddit engine is an effectively-unsupported blob of code that needs tons of other heavy dependencies to get it running. The only site I know running a copy of the Reddit engine is LessWrong—and they've heavily forked it for their own purposes.
For me, Reddit works pretty well and it's very easy to avoid the worst bits.. and to be honest, like you, I find a lot of the comment sections on mainstream news sites and places like Youtube are much, much worse.
Who defines what "acceptable" behavior is though? If so many people "wouldn't recommend or even admit using in a mixed group", then why is Reddit the 8th highest traffic website in the US?
My wife is annoyed because I spend time here but just because of the time I spend not because of anything that shows up on my screen; most of the bad stuff people write about just doesn't seem to cross my path.

People talk about free speech like it's some goal, but in reality all people seem to do with it is make fun of fat people and post stolen naked pictures of celebrities.
When confronted with the fact that this isn't acceptable behavior, even if you specifically don't ban them, they will threaten you with death and ddos your site.
"Voat has been under constant DDoS [distributed denial of service] attacks almost since Day One. At one point, our servers were shut down by our ISP without notice. We even received death threats."
Instead of lowering the bar and getting surprised when people fling shit, Imzy is trying the opposite.
Will it work, no idea, but free speech as much talk as it gets doesn't work out as well as some people like to pretend it does.
