For a start, 'real' lefties should seriously consider
the back-firing damage they cause our movement
by persistently conforming to alienating stereotypes which keep us out of power...

Understand and know our tory enemy.
If it helps, to dress and look like them as a confusion tactic.
New labour made the mistake of dressing up in expensive suits and ties..

Personally I look and talk like the kind of ordinary bloke in the street
who might read tory newspapers and support UKIP.
That's not an elaborate constructed disguise,
I've always looked like that.

(Apart from a few days when I was a student and had purple hair,
after getting drunk at a party with a Bristol punk band)..

Pass undetected mingling with the enemy
engaging as much as possible in constructive rational conversation.

We only shoot ourselves in the feet if all we can do is browbeat and lecture folks with textbook ideology
from on high,
looking down on them
from a crumbling ivory tower vantage pulpit...
