Who would wish to commit on the internet to an idea that may be (legally) used against them? Well if someone were to say, "all X are scum", then yes it's racist. But if it is a reasonable discussion about targetting resources or undertaking research then I can't see how it's racist. It just seems a little strange to a liberal like me that in the current news cycle it seems acceptable to be rather rude about Eastern European migrant workers - like the recent news articles that they are all benefit thieves, or all drunk drivers. It's just my sleep deprived brain throwing this idea out there for discussion.
