I take your point but for me it wasn't about being upset easily, it was more about principle. I did not at the time want to support a site that seemed ok with racism. Other things I find a challenge are when violence is advocated, such as execution of those who hold a different view.
I do wonder where the line in the sand would be? What subjects would not be allowed? For instance if someone was advocating ethnic cleansing, torture, paedophilia, just to name a few examples, would that be allowed? I just don't think all this has been thought out. The only rule now seems to be that you aren't allowed to abuse other members. I would hate to be a mod at present.
All the pitfalls of Twitter and Facebook mixed with the trappings of the MSM. There is no escape other than avoidance as if one could.
