I agree with Andrea, C4 love the fights and arguing because it pulls in the viewers.
Every year Davina says that BB is getting tougher and stricter on housemates, but it never does.
What confuses me was that BB removed Dennis for unacceptable and threatening behaviour. If thats the case BB should have removed Stuart, Dale and Rebecca also, so getting in peoples faces and saying things like "what you looking at". These are trivial BUT can be seen as agressive and theratening behaviour also. It makes no sense, it seems that BB only punish the housemates who could in turn get BB into trouble, so race and homosexuality arguments, thus the reason Alex and Dennis were removed.
I admit watching BB, but it has now run its course. persoanlly I prefered the BB Hijacked, that was much better!
