May its just me but it seemed a little racist when...

Maybe its just me, but does anyone else think the scene (in the railway camp) where Carver goes for his horse was a little racist - and completely unnecessary? In case it passed you by, Carver goes to get his horse, some Chinese immigrant workers are in his way and he then bitch slaps the hell out of one and they all go into submission mode.

I get that the Chinese immigrants were treated like crap but this scene makes no sense and doesn't really seem to serve a purpose either!
