Ive given up on resolving disputes with those people  Frankly resolution is not possible  All you have to do is look into his contributions to see an obvious pattern of vandalism  It does not take an expert on the subject to figure out whats going on there  What you dont seem unable or unwilling to understand is why those users are editing articles on Wikipedia in the first place  There are two possibilities  i You dont have a history with these guys or ii You are involved in the same activities  You have made it quite clear where you stand though  You are as guilty as they are of corrupting the integrity of those articles whether it is intentional or not  Have a good day
