well you can't blame some people being on edge after a group of trolls just infested the board, one posting 30 different threads and new members coming up in the same day. I wouldn't say its hostile, many members have just been jaded over the years and find it hard to give new guys the benefit of the doubt, espescially when the board was just harrassed by trolls.
As far as the arm length thing, just watch fights between blacks and whites that are similar height and notice the arm measurements. Also, you can find arm length measurements from NFL combines. I don't think its that much of a difference, maybe by a couple of inches at the most, and I would say that is on average, not always the case. I don't follow boxing closely but I know it is usually used to discriminate against Whites at the left tackle position in football, saying they do not possess "ideal arm length" when they are usually about a half inch or inch below what they list as being ideal. Then you compare these White tackle prospects to the White left tackles currently in the league and their arm length is usually similar, but guys like Joe Thomas are said to be "the exception to the rule". Like one inch is going to matter when going against a speed rusher, unless you want to commit a holding penalty and grab onto a jersey or helmet as they fly by (which commonly happens with sumos, rarely penalized).
