You have perfectly described the whole point of the RW led culture wars.
The problem the left has is finding an answer to these accusations.
Personal pronouns, its not a Socialist issue, it is a liberal issue, an issue that the RW of the Labour party with their metro sensibilities think is liberating, to the working class base it doesn't fucking matter, me personally I couldnt care less about it, i am more interested in whether the pronouns are being fed, have homes, have access to good education etc than if they are Mr, Mrs , Ms or whatever else they want to be.
Is anyone really concerned about our colonial past, if the people behind the culture wars were concerned then why is it not taught properly, warts and all. By all means teach the good bits, but teach the bad bits too. You do not learn about Fascism by saying they built great Autobahns, you learn by what bad stuff they did as well. So teach that the Empire was built on the backs of colonialism, learn how the subcontinent was exploited, its industry closed down so Manchester could produce textiles to sell back to the subcontinent, learn the reasons why it happened, do not ignore it, it happened. It doesn't make the UK any less of a country, it makes us a more honest open country willing to accept we made mistakes as well as doing a lot of good. Learn that we used slavery to populate cotton fields to pick cotton, to send to Manchester to make textiles to sell to India and use the profit to buy opium to sell, learn we were basically drug dealers. We don't have to apologise for it, it is nobody who is alive who is at fault our ancestors were cunts. Ignoring history though is wrong, rewriting history is wrong. It is a fact that Great Britain became the biggest colonialists of all and they did so because we had an abundance of Oak trees, that we used to build the worlds greatest navy. Teach it all, warts and all.
I steer clear of the Palestine issue, but there are people who see it as a re-enactment of the aparthied struggles in South Africa. They may have a point, it is a fringe thing though and not really as widespread as is made out. It has been used though to paint the left as antisemitic. There may be some antisemitic stuff thrown around, I dont do it and nobody I know does it.
As for Patriotism, it was always the left that was Patriotic, it was always and will always be the working class that do the majority of the dying in the name of Queen of country. Personally though I get sick of having flags rammed down my throat as waving a flag does not make you a patriot, caring about your community, caring about your fellow man and caring about countries good name makes you a patriot. The cunts waving flags and ramming Englishness down peoples throats are not Patriots they are Nationalists, and as Orwell says Patriotism is defensive it is a love of your country Nationalism desires power and seeks prestige. it is not love it is driven by avarice and it is offensive.
The Labour party was formed as a party for Workers, it was aspirational for workers who had long been downtrodden and unrepresented in the corridors of power, it wanted power for the working class, it wanted the working class to be better and be given life chances like those of everyone else. That is aspiration not the corrupted Tory version of aspiration where what you own is more important than what you are. In Socialism there is no room for idleness, everyone works, the goal is always full employment, it is the capitalist class that do not like full employment because full employment puts power in the hands of the workers and they can demand a bigger slice of the pie.
Of course Labour should stand up for minorities, but Labour should also stand up for majorities too, because Labour should stand up for everyone. We already have a party in government that governs for a minority, although the capitalist class are never portrayed as a minority, but they are and they are the ones who hold power and treat us to these ridiculous culture wars so they can stay in power. They want what is there's and what is yours, that drives inequality and the thick fuckers do not see that by pursuing this narrow minded agenda they create inequalities amongst themselves.
As long as people fall for these culture wars though Labour has no chance of power, when flag waving is more important than feeding kids, singing the national anthem is more important than building decent homes and salivating over statues of long dead anti-heros is more important than building houses then this government and its cronies can carry on with their systematic rape and pillaging of the nations treasure,
