British Tamils protest against Sri Lankan President M. Rajapaksa for war crimes by Waving LTTE flags, a banned terrorist entity in the UK. These people support terrorism, suicide bombers and child soldiers but are calling for war crimes against a head of a state who fought terrorism (with questionable techniques).
I'm no fan of the tyranny of Rajapaksa and his family exerted in Sri Lanka and their tactics to suppress minorities and any one who questions them, but if people are not willing to condemn the terrorism of LTTE, then suck it up with Rajapaksa!
There are good Tamils and not so good Tamils everywhere, but the bad ones are a minority. If you get to know the good Sri Lankan Tamils you will really love them, they are very nice people, but for the pro LTTE ones who are racist and anti Indian Tamils too!
