How can it NOT be treason if someone fights against their own country?
If you choose to live in a democratic country you support them. If you disagree with a government's ideas you debate, vote, lobby, educate or whatever. If you still don't like it then you emigrate elsewhere. Fear or violence against a democratic nation should never be condoned.
Skylark4 'if they want to fight for the Taliban they must want to live under their rules for the rest of their lives'. Exactly. They shouldn't then be able to call themselves British or benefit from a free British education, health service, income support, etc.
I'm all for cultural diversity & freedom of thought, speech & religious belief, but it should never be used as an excuse for ignorance & violence.
Max R8, I agree that 'all those who wish to fight against their "own" country are traitors..... that includes any terrorist organisation' BUT how did you then jump to '....and wives of Kings who commit adultory'????!!!! Sorry, can you explain the logic please.
