I'd personally try and avoid using words like 'triggered', as it kind of suggests people with opinions is a bad thing. It's kind of passive aggressive, along with the likes of 'snowlflake' and 'fragile' and all that bollocks. It's implying that someone else's opinion is less valuable because of their reaction. It certainly doesn't help resole anything.
What Liam did, was lay bare the general opinion of black people in our society by people who don't necessarily consider themselves racist. People of all colours and creeds are capable of racism but I'd say Liam touched a nerve and hopefully the discussion around it can be positive, in the long run. A certain ex-member of this forum let a similar incident turn him into a Stormfront bitch, so it's certainly something that needs to be examined.
I agree about the hypocrisy. it is sickening.
