It's men vs. women (feminism), ethnocentric vs. non-ethnocentric (biased narratives in favour of certain minority groups, i.e. tolerance and diversity), immigrant vs. resident (multiculturalism; if Blair didn't import 4 million migrants to 'rub the right's nose in diversity' there would be no divide and rule, people wouldn't even have a problem with immigration), Islam vs. Christianity (i.e., Tim Farron being questioned on his views on homosexuality in a way an Imam or Islamic leader never would be), young vs. old (lower the voting age!), rich vs. poor, etc.
The Guardian, for example, is just perpetual divide and rule; it doesn't advocate policy, all it does is advocate groups rights ahead of individual rights and prioritise self-interest and preferential treatment for the groups it manufactures oppression on behalf of.
Progressivism is all about identity, not policy. It stipulates that self-interest is perfectly acceptable if expressed by non-white, non-British residents, but when expressed by British residents it's the precise definition of racism, rape culture, xenophobia, sexual objectification, sexism, misogyny, Nazism, fascism, bigotry, little England, the old boy's club, and every other exploitative narrative they care to utilise to make everyone conform to their politically correct group think.
'Reverse racism (racism against white people) isn't real', the Huffington Post.
'White men should never hold elected position in British Universities again', the Independent.
'I prefer being around black people', Guardian author.
'White homosexual men must stop co-opting black female culture', NUS conference for women.
'White men should be banned from attending diversity events', Goldsmiths University diversity officer
'It would be rude to interfere with a Labour Party event segregated along gender lines to appeal to Muslim voters', Harriet Harman.
'We should tour schools teaching boys not to hit girls', Harriet Harman.
'We need to teach men not to rape', Salon, the Guardian, etc.
'St Andrews golf club shouldn't be male-only' (the BBC, despite hundreds of thousands of female only taxi firms, political party conferences, business conferences, gyms, workplace awards, networking groups, etc).
It goes on and on. The left is perpetual divide and rule and identity and group rights are always prioritised over the rights of the individual - all it knows is shame and guilt.
