"Other Parties do not have that problem."
Most parties don't have factions - they have no dividded loyalties between self interest and duty to the people who they are supposed to represent - their loyalties are overwhelmingly to themselves and the privileged - the people may go stuff themselves.
The Labour Party, down the years, has moved further and further to the right; Blair, a possible war criminal, with the help of a couple of self-serving idiots and a soft-porn journalist, confirmed that rightist position with his 'New Lablor' coup.
A principled leader, Corbyn, presented the possibility of returning the Labour Party into a decent, honest part, which now has the establishment running around like headless chickens, trying to bring him down, which is basically what this is all about - why should a pair or extreme rightists like you youd your pontificating friend bother your right-wing arses about what happens in the Labour Party otherwise.
So far, you have failed on every count, just as you are floundering here.
If you think in-fighting doesnt take place in other parties
DREAM ON
AND ON
AND EVER ON
AND SO ON Ad INFINITUM
What planet do you live on?
