We have a coalition

The Tories and the Lib Dems have formed a coalition in the UK. As of now, some policies I fully support have come out of Downing Street - taking people earning under £10,000 a year out of income tax and the scrapping of ID cards are examples. Now they're saying they're going to repeal some of Labour's more pernicious intrusions into civil liberties, but is this a smokescreen? I can't help feeling we're being softened up for some very harsh cuts, which any party would have to make. I voted Lib Dem (a pointless vote since my constituency's Labour MP was returned with a majority of over 15,000) and I'm willing to give this coalition a chance. I was initially very angry about it, as were many and I think the Lib Dems will be demolished at the next Scottish Parliament elections next year.

So:
Is "tribalism" the main reason behind opposition to this coalition?
Is the right-wing press going thoroughly mental about it a good enough reason to support it?
Where will it potentially fall down?
