Dual wielding citizenship shouldn't be second-class citizenship. A British-born person can be the shittiest asshole, doing terrible illegal things without any respect and decency for their native land, and it's cool. But if you bear an additional nationality, that's it! you get out of my country.
Where do you draw the line though? At what crime? Do you realise you are treating all binationals as lesser citizens, subject to different laws just because they happen to be born in a different country? There is already a clear line, which is drawn at giving the citizenship to someone. If a foreigner commits a crime, he's expelled. But once we decide someone gets to have the citizenship, he should be treated equally as any other citizen.
I think we should be able to look at a child rape/sex ring case without going "but what about x!". This happened, this ended up in convictions, and this is a reality.
If you can accept a country can legally revoke your citizenship after accepting you, what exactly are you arguing for, that countries SHOULDN'T be able to do this at all? I think you'll find most can, and most do have very precise and stringent legalities around it.
I'll guess there are some American posters in here, so ~

Grounds for Denaturalization
Although rare, it is possible for a naturalized U.S. citizen to have his or her citizenship stripped through a process called "denaturalization." Former citizens who are denaturalized are subject to removal (deportation) from the United States. Natural-born U.S. citizens may not have their citizenship revoked against their will, but may choose to renounce their citizenship on their own.
This article covers the grounds for having one's citizenship revoked, the basics of the denaturalization process, and defenses to denaturalization.
I'll point it out again, in the UK you are protected from ending up in a position of
statelessness.
Because I can see the big picture. Do you trust this government with the power to strip citizenship away from immigrants? Especially when they can use the good old "Ah, we can't actually tell you the details of what you're being charged with because y'know, national security"
Fuuuuuuuuuuuuuuuuuuuuuck that.
Yeah, that's why they're being locked up for decades. That's the punishment for being despicable human beings, the government shouldn't be able to tack on extra punishment because they're a bit foreign.
You're arguing about the "big picture" in your head in a topic about convicted child rapists/traffickers? This is the kind of topic you read and thought this is a slippery slope? I'll say it again,
convicted child rapists/traffickers. This has nothing to do with conspiracy theories and "fear of the big bad government". These individuals have also been able to have the chance to appeal, and that is what this topic is about, their appeals were turned down by a judge, in a court of law. No one is shipping them off out a back door in a wooden crate without any legal jurisdiction.
