no argument to be had.. Suffice to say that anyone who professes to be Vegan, yet is happy to burn animal based fuel and kill innocent insects on bikes riding on tyres derived from decomposed sea creatures whilst possessing a mouth full of teeth best suited to a carnivores diet, seriously needs to address their denial... compromising personal safety by refusing to wear animal based protective clothing is, in my opinion, not only hypocritical, but its also crazy!! And like all other conversations with vegetarians/vegans, i bet the above comments result in personal insults instead of constructive, adult discussion.
