what it means.... unless you have an internalised subjective opinion of your own that clouds it.

bear, the bore and the easylay make up loud, messy, noisy oi oi louts

ricky, james, sam, frankie make up tidy, respectful and basically "nicely" behaved people.
(frankie is noisy but only when doing his set dance pieces normally to a set pience like music or a task)

so that is what she likely meant by nice...

unless you particularly think differently

She meant these are the people I like.

subjective.

in a house of louts and reserved people...
when she was talking about the reserved people
she was right to call them "nice" as a group

if you don't think bear, heavy, hoe and aggressive are louts, well you might have trouble thinking they arnt nice and hence the confusion over her labeling the reserved people as nice when you see it as a bias to what she thinks of them.

No - she was certainly not right to call one set of HMs 'nice' as it suggests the other set are not nice.

It is not up to her to make such distinctions. It is up to the viewers to make their own minds up.

And then if they choose to pay money to vote for a particular HM, they are safely doing so without any prompting from the show - namely its presenter.

The show has to be impartial or else the voting becomes a mockery.

What next? Are we going to sit back and let her say 'These are the nice HMs and I very much hope you are all voting for them!' 'If you vote for X HM then you are an idiot to condone such disgusting behaviour.'?
