If it's your father who dies alone because you ca't get to him due to groups illegally blocking the road, or if you've know people be delayed getting to hospital when they're losing their baby, or an old lady late to a hospital appointment for a scan (who later died) due to an anti-fracking group blocking the road, you might count it as serious. No, these things couldn't be called murder, nor will the people who stood in the road to protest against fracking think it's wrong that a little boy was in tears because his mother was late to collect him (the normal road she would have used was shut due to an RTA, and she was forced to deter down a road that should have got her to her child only ten minutes later, but due to protesters bringing the traffic to a standstill, she was half an hour late to pick up her child- a little boy who had just been diagnosed with a serious illness, and whose mother had not long been out of hospital-and he thought she'd died because she was so late, but the people blocking the road will simply say it's for his own good. Just as anti-abortionists will say they have the right to protest outside clinics, never caring about what they might be doing to someone's mental health-or physical, if the woman is too afraid to seek help for physical problems after an abortion. Is is terrorism? Many would say legally no, morally yes.
