First, vocal and influential Ruby developers talk about this. I've heard Chad Fowler, DHH, and Matz all talk about it at major conferences (RailsConf and RubyConf).
Second, I've worked with dozens of clients on Ruby projects, and talked with dozens more, and I've never heard these sorts of issues come up. Outside of the language war world, people don't really care if DHH swears or if an inappropriate presentation is given at a minor conference.
They sure do:

why has a point.
There's plenty of evidence that DHH and some other prominent ruby developers simply don't care at all about people having different perspectives, and they certainly don't respect it. These guys want to use their work in software at a platform for their little personal identities. The "community" is absolutely not welcoming; it's actually outright exclusionary. They don't care, and they don't even pretend to care.
I primary work with ruby and have for a few years now. I'd like to continue to do so. But I'm frequently discouraged by the fact that involvement with the community means dealing with people who are simply not nice people.
