While this is true, it should be well-known that there is a not insignificant chance that the police will kill unarmed black people (or other minorities and sometimes not restricted to them, though less frequently), and that calling the police to deal with a situation involving black people will often end with innocent people being murdered. That should factor in the decision to call the police.
Provided Houseman has a correct source (a big if), you can look at the picture he posted of the kid's toy, comparing it to a real firearm. I personally could not tell which was real and which was not. I do know that toy guns are supposed to have an orange tip on the barrel for exactly this kind of situation, and this one does not.
If you got somebody running around with something that looks just like a gun, what are you supposed to do? Run up to them and ask to test fire it to see? Or call police? I don't give the caller any blame in this case.
This sounds very much like you didn't watch the video
Edit: Alrighty, specifically here are my problems with what you said and pretending your linked video backs up your point
1. The video outright states that the troll does quips, not detailed explanations. Houseman does not fit this all the time. He give some very detailed description. Assuming he is a troll, based on this assessment tools, is a bad assumption
2. Not specifically engaging with Houseman may be a good tactic. Perhaps that's what you meant by your comment. But not specifically engaging with the ideas is terrible.
3. This video is not about 'not reacting.' It's about changing your reaction
4. 'Not engaging' is a reaction in and off itself. It leads to a default win because you were scared off. It encourages trolls
Frankly this sounds like denial that you guys have let Houseman masturbate himself all over you for two months and continue to enable him doing so. I can't figure out why, personally. It's as if you don't remember his post conduct going back years, before he was banned. He thinks he is a god of reason and rhetoric, and the simple act of arguing fuels him. He will take the worst, most stupid positions just to have something to argue about to "engage in discourse." You guys are absolutely, positively feeding him.
Man, I remember the first week he showed up on Arnox's spin-off free speech forum, he made a thread asking "How Are You Better Than Hitler?" And all the thread was just people posting their reasons why they were better than Hitler, and him arguing about it.
Maybe that's context which I have that you guys are missing, but I honestly don't think you need it.
