Not doomposting, as tempting as it is, since at least this particular flare up established the precedent for violent reaction to non-whites murdering whites. If this kind of thing is being discussed at all -even
negatively- by the wider society, the Overton Window has already shifted. If they want to have more of an effect next time, take a page out of the semi-successful trucker protests in Canada and actually do something that hurts more than throwing garbage bins around. We're talking blocking off key infrastructure to the cost of millions or billions, and locating somewhere that is an impossible-to-ignore embarrassment for the government.
Yeah, that'll sure show the Pakis.
In all seriousness, English as a global language is a double-edged sword: it makes the UK much more attractive to hordes of foreigners, since it's the most common language the third world learns after their mother tongues (if their mother tongues aren't already English).
They already do.
Just, erm, a tad selectively.
