>Was the Barbara Pit massacre justified?
That's up to you, bud. I mean, I'd say it was pretty justified. Considering both the state that the former Yugoslavia is in currently, the conditions that led up to the massacre and what they created out of the ruins of WWII, you can definitely see why it happened. But then again, I've never killed someone, I didn't live through those conditions and neither have you.
>How do you refute "anti-white" racism spooks?
If they're rich, you can't. Steal what isn't bolted down, vandalize the rest and make their life a living hell to the best of your ability. If they're working class, chances are the things they perceive to be "anti-white" racism (like being passed up for a well paying job because a black guy got it instead or some shit) could be directly attributed to capitalism's blight (well, everyone should have a decent fucking job, I don't blame the guy who got the job, he wanted to put food on the table, too). Hammer home class as much as possible, connect their issues with the issues of people who aren't white. If they're complaining about "essjaydubs on the internet say white people are evil", point out how everyone saying that won't even touch social democracy with a 50 foot pole. And be less of a dick than I am usually.
>are state-owned companies really unprofitable, if so how do I defend the concept of state-owned?
1) Not always, no. If you're a burger, see the USPS. Not only is it significantly less shitty than UPS or FedEx, it makes money and only has financial woes because of having to fund pensions 75 years in advance.
2) For state-owned industries that don't turn a profit, point out how them trying to would make them significantly shittier, and how the market can't or won't meet everyone's needs. Healthcare usually isn't profitable, but not only do burgers pay out the fucking nose so it can be, it ends up being either shittier or just non-existent to state-ran healthcare.
all of it
