It’s no big deal that Islamic terrorists can keep tons of bomb-making material - what they do with it is no one’s business. The state is too busy cracking down on the real crime of hate speech to worry about what someone theoretically might do if they made a bomb just because they happened to have the materials. The main thing is, the average Brit has to register his knives and is prohibited from carrying even a small knife, and his speech is monitored for hate and this keeps everyone safe. /sarcasm
