I'm Liberal but to a degree

Walking through Tai Po Plaza yesterday, I found that the Liberal Party's district office there had disappeared.  I assumed that, with no election coming up in the near future, they had decided to bugger off back to their luxurious homes on the Peak, but in fairness, I find from the party's website that they still have an office in Sheung Shui.

What is it about political parties' names?  The Liberal Party isn't; the DAB ("Democratic Action for the Betterment and Progress of Hong Kong", which should surely be in the Guinness Book of Records for the world's most unwieldy party name) does not support democracy and has never bettered Hong Kong; and the Chinese Communist Party long ago ceased to practise anything Karl Marx would recognise as communism.  Other countries are no better: Britain's Conservative Party has not conserved anything worthwhile for decades, though it has destroyed much of value; Japan's Liberal Democratic Party is neither liberal nor democratic; and so it goes.  In fact if a party named itself the "Bunch of Corrupt Self-Serving Shoe-Shiners" it would be so refreshingly honest people might even vote for them!
