It won't refuse entry to folks from Eastern Europe or North Africa who put a drain on public finances (by living off the dole) or represent a clear and present security threat (by actively encouraging, or actually participating in, terrorism). It won't deport people who openly call for the murder of non-Muslims.
It will, however, bar political and social conservatives from coming to Britain. (To be fair, it will also bar certain stripes of legitimate hatemongers, like Fred Phelps.)
If this wasn't so pathetic, it would be comical. If I wrote a fictional story depicting something like this, no one would believe it because it would be too much of a PC Lefty caricature.
The funny thing is, I agree with British Home Secretary Jacqui Smith's rational for barring people.
I think it's important that people understand the sorts of values and sorts of standards that we have here, the fact that it's a privilege to come and the sort of things that mean you won't be welcome in this country ... Coming to this country is a privilege. If you can't live by the rules that we live by, the standards and the values that we live by, we should exclude you from this country ... It's a privilege to come to this country. There are certain behaviours [sic] that mean you forfeit that privilege.I'm fairly certain that if anyone wanted to apply those words along non-Liberal lines -- if, say, they wanted to bar followers of sharia -- because of the effect such people's presence would have on the country, Ms. Smith would be apoplectic. I couldn't express my feelings about immigration much better than she has, though.
