I am not condoning Kasparov and his action or otherwise, though I think it misguided.
Ichkeria, the age a law enters the system is irrelevant be it 2001, 1961, 1861 or 1361, it is the appropriateness. You are welcome to enter your local cathedral and sing a song against David Cameron, Nick Clegg or even Ed Milliband and then chant obscenties against the Queen, the Royal Family or your local bishop. As an aside, you are even welcome to cuss the Archbish of Canterbury - I am not his biggest fan, anything but.
I look forward, though, to reading about you your protest, charges, trial and sentence, not only in the Times and Telegraph, but also in AOG's bible, The Mail, and even Gromit's left wing rags. And also here; I can just imagine the brouhaha.
