Exasperated, not angry.
Essentially the implicit message of this section is that foreign workers are being dumped in Britain and exploited and we should oppose the free movement of labour.
While I agree that the section in question is written very very poorly, and I wouldn't be happy about going door-to-door round here promoting it, but I also don't think it says what you say it does.
For one, it is in no way explicitly 'anti-immigrant', or however you phrased it before, and I take it from your belateed silence on that front that you now accept that.
But also what is being discussed in that section is explicitly not the 'free movement of labour'. It is the movement of tied labour, labour effectively owned and controlled by company bosses, who move workers around he world in order to maximise their profits, under-cutting locally agreed T's & C's as and when they can. Opposing that is not opposing workers themselves deciding where hey want to live and work.
