Local fishermen have come to believe that my research will negatively affect their livelihoods. Following your logic they would be in their rights to burn my boat and rip out my experimental plots. I don't think so. You also cannot compare the treatment of animals to the treatment of humans. We affect change through non-violent protest and by presenting well thought out and well documented arguments.
Violence begets violence.
Or do you believe that I should stop because someone objects. If the latter is true then might I suggest that some would find your research objectionable and thus maybe you should stop. Mention of trade names or terroristic actions should not be construed as support for these products or actions.
