For me the issue is about understanding in a real way what people think, why they think it, what the implications are and what the solutions are, all with regards to immigration. That's what the thread was originally about, but literally the 2nd reply turned it into a discussion about racism. Anyone suggesting they aren't linked is kidding themselves, but the same is true of people who think it's the only link that matters.
The thing is, of the three people that replied to me, two of them immediately brought emotion into the discussion. You and
@Kentonio both immediately decided I was upset / offended. Despite the fact in my very first post I said people can say whatever they want, making it pretty clear it's not something I'd be remotely offended or upset by. If you were here next to me you could see how ridiculous that is. Offence levels are 0.
I actually called my mum a racist in that moment, shocked at what I was hearing, and typically speaking my views would be quite close to yours on this. On reflection I changed my mind though. Or rather I softened my stance. In part because of some interesting studies posted by
@PedroMendez on the link between social cohesion and immigration, among other discussions on here, which illustrate the complexity of the issue in a way I hadn't personally considered. So I also agree with you that you can have more open discussions on here than in many places.
In spite of that, you made an assumption about what my point was, an assumption about what my emotional state was, and an assumption about my intentions, all while telling me I'm wrong and placing yourself on a moral high ground. That's before any attempt to discuss things took place. That belies your suggestion that talking about immigration is a perfectly possible conversation. Sure, you can grit your teeth, ignore all the insinuations, and calmly make your point. But you aren't encouraged to do so. What you've done is actively discourage that, despite evidently being quite a reasonable person.
I personally don't think my mum is a racist, despite saying something I find alarming, confounding, disheartening and many other things all at once. I have racist family members and I have a couple of particularly racist friends (of friends) who have a genuine hatred of aboriginal people in their area, for reasons which are outrageous in and of themselves. To me the difference is quite stark.
You could argue that I'm just distinguishing between casual racism in my mum, and active, targeted racism in my friends. You could argue that casual racism is actually more damaging to society given its prevalence. And you could argue that my own acceptance of that, and what that says about wider society, is perhaps the biggest challenge to overcome. You might well be right. I don't personally think so, but I do think it's incredibly complicated and understand the varied views on things. I also think the over-simplification of the issue, as happened in the 2nd reply to this thread, is a really serious issue and a very counter-productive approach. Which was my original point.
