First off: there are no important video game issues. None that are more important than basic respect for other human beings.
Secondly: this is entirely about being respectful. Just because being insulted doesn't hurt your feelings doesn't mean you should put up with it. If a kid talks **** to me, I don't care, but I'm damn well going to tell their parents what a little ******* they're being.
If someone's insights are so valuable, then it really shouldn't be a big deal for them to show a little respect to others. In my forum, that stuff will get you an instant mute, and a swift ban if that doesn't take care of it. It has nothing to do with protecting the tenderfooted. It has to do with having a positive community. This is not the shark tank of big ideas, so there's really no justification for that kind of behavior. If you want drama, there are better forums (re: most of them) who specialize in that.
I'm not sure if I can expect someone who throws around words like "******" and "crying" (as if expecting civility of others makes one overly sensitive somehow) to agree. Personally I find that sort of attitude always comes from people whose contribution is much less meaningful than they think it is, and is generally rendered a negative worth by the time they start gracing others with their perfectly harmless (but still utterly stupid and immature) vitriol.
To me, talking **** is weak. You clearly understand that on some level. So when you need to punish a child who is determined to act out, you do something that has power. You don't argue with them. You give them a smack on the ***, and promise another if they don't straighten up. And if you're not the parent, then you tell the parent that their kid needs a smack on the ***. That's all that's happened here. Ostia just flew a little too close to the sun and got his spanking in public.
tl;dr:
I've met my share of people who assume that complaining about someone's behavior or punishing someone indicates that they're butthurt. They are usually too immature themselves to even understand what it feels like to deal with a behavioral problem without getting upset or angry. They only know how to either ignore a nuisance or get emotional, so they choose the former. As a result, they develop no skill at resolving interpersonal conflicts constructively, and are completely worthless at dealing with behavioral issues. I see these ****** "no big deal" parents and would-be professionals all the time. Conversely, there are actually mature people out there who have learned how to get in the thick of it and still keep their cool. They just do it, because someone should not be a lazy piece of **** and get something done.
