Ilovecheese, in regard to your post @14:23 today, the Labour party avoiding "bad press" would seem to many a sensible thing to do, and in that singing the Labour Movements anthem in public situations should be avoided. Tony Blair in his years as leader of the party ensured that his administration (in the main) kept the mass media on side by not bringing forward radical policies or actions.
However, to achieve the above Blair constrained input into the party from district and constituency parties and affiliate members along with their organisations. That restricted debate and policy creation in the party to a close group surrounding Blair and Brown. Many in the Labour movement today believe that structure gave Britain the beginnings of Zero Hours contacts, the Gig Economy, the British end of the Banking Crisis and the Iraq War.
The Election of Jeremy Corbyn once again opened up the Parliamentary Labour Party to input from all connected to the Labour movement, it's affiliate organisations and their membership. The days of Blair as leader are decried by large numbers in the party and especially in the trade union affiliate membership. These days those members pledge that such organization and policies will never be embodied into the Labour moment again.
Therefore, today we have i believe a Labour party and broader movement that has brought forward an organisational structure and policies that it firmly believes in and in that assumes an attitude that the Electorate will accept those structures and policies or not, but either way, and within that nothing will change.
In short, the party and broader movement exude an attitude of, we have our structure, we have our policies and along with that, if singing the Red Flag as our anthem draws criticism from the mass media and sectors of the public, too bad. We are what they are for better or for worse, and so shall remain.
The above is a stance which i feel they should long continue into the future.
