For starters, I wish to state that in an issue like politics, extremism among some individuals is inevitable. There are two reasons for this. First, many people mistakenly apply religious impulses to politics and thus attempt to be consistent with a certain political viewpoint, even at the expense of ignoring or denying clear empirical evidence that is against it. Quite simply, it is easier (if you are intellectually lazy) to just blindly follow a dogma of some kind that happens to appeal to your ego than to dig for the truth, apply consistent logic to all issues, and thus have a perspective that is subject to change and moderation over time. Second, extremists on any issue tend to work the hardest for their chosen causes and thus tend to rise to leadership positions within political organizations as well as single-issue pressure groups, by virtue of their extensive track record of having done so much for their causes as well as appearing to be experts on the issues they represent. This explains why so many otherwise worthy causes, such as animal rights, get so absurdly corrupted by groups that claim to represent them, such as PETA or ALF, and people who might be motivated by natural compassion to support animal rights are repelled by seeing extremist groups like the aforementioned ones claiming to be the best examples of those causes’ representatives. Let me assure you, they are not and I would be quite happy to see them destroyed without thinking for one second that this would be damaging at all to the cause of animal rights. If you, by your words or actions, make a cause look loony, that’s the best way to ruin it, and you might as well just oppose the cause altogether.
