In reply to winhill:
You still haven't been able to identify a UK source for your bristle, you still haven't been able to demonstrate a mechanism of cruelty and now you have been found out in lying about the well documented controversy, you're claiming it was a FOAF who told you.
I said "let's hope it's UK bristle, and especially not imported from the Far East" because it seemed reasonable to assume that bristle from UK-farmed boar would be commercially used, being a potentially valuable product. I don't know for a fact, however, that any bristle is commercially produced in the UK. It also seemed reasonable to assume that (in the UK at least) if boar were regularly pinned down (unanaesthetised) and their bristles pulled out with pliers, the facts would become known, and there would be an outcry. My basic point was that much of the world's bristle comes from China, but, effectively, any ethically-sourced bristle would have to come from elsewhere, because a specific code of humane practice would be needed: Chinese boar farming practices are largely unregulated, and cruel practices tend to stay much more hidden, and for much longer. Say what you like, the humane treatment of animals is simply not on the agenda in China, and the information that has emerged in recent years paints a very black picture indeed.
"Demonstrating a mechanism of cruelty" (sounds alarming!): I am waiting to hear from a number of organisations (offices have been closed for Christmas), after which I very much hope to post links to documents and at least one video which specifically relate to the bristle industry. In the meantime, for anyone who doubts the Chinese penchant for cruelty to animals in general, do a bit of surfing. Maybe Google "Chinese fur farming", or check out the PETA website on that topic. You'll need a strong stomach.
Regarding the FOAF comment: I didn't say that, or anything like it. The controversy exists, as does the evidence - I've seen some of it myself, a few years ago; however, it has proved difficult to turn up with a quick bit of Googling. So, yes, in terms of what is immediately available with minimal effort, not as well-documented as I anticipated. Unfortunately this is often the nature of it: governments are not quick to publicize details of institutionalised bad practices; even in the West well-funded and officially-reported investigations are very thin on the ground. What we do get tends to come from well-motivated but relatively poorly-funded independent organisations, usually working under the constant threat of crippling legal action. It's no surprise that their archived material tends not to be left in the public domain.
On a different tack, I'm curious about why you're so angry about this. My posts on this thread, I think you'll have to agree, have been reasonably calm and tolerably polite (despite the subject matter being something about which I feel strongly), a style in which one should be able to debate, I think, regardless of differences of opinion. Yours have been consistently and unnecessarily rude, and have verged on ranting at times. The number of times you've used the words lying or liar outnumbers my posts about three to one - I can almost feel the flecks of spittle hitting my face! I had a quick look at some of your other recent posts, and they don't generally seem unduly ruffled or aggressive. I can only assume it's the subject under discussion: it seems you're one of those people who've developed a pathological hatred of "animal rights types" (for want of a better term).
Judging by a recent thread with a political slant, you clearly have some intelligence, and some skill with language, but in this matter I think your anger has clouded your better judgement. You have now stated that "... bristle is such an innocuous by product ...". I don't see how any reasonable person could state that as plain fact, not allowing (at the very least) for some uncertainty in the matter. Earlier in the thread you threw out the accusation "this isn't about the animals, it's about you". I would hope that by volunteering some historical details about myself I have shown that I do genuinely care about animal welfare, enough to have made some long-term commitments. Let me now turn it round, and ask if you yourself have any genuine desire to get to the bottom of this. Do you think animal abuse is something we should be concerned about? Because what seems of paramount importance to you is to find a way, any way, in which to dismiss any allegations of animal cruelty.
