This wasn't really an argument imo, more like a conversation in which Roland could gauge Richard on his ideas. Yeah, they argued over the claim about america being a white country, but it didn't go anywhere of substance imo. Also, I have no idea what point Roland was trying to make regarding the benefits of mass immigration; he implies that mass immigration would be fine based on the results of immigration in the earlier 1900s, which is nonsensical for an assortment of reasons. The two main ones being that immigrants back then had to pass a set of criteria to get into the country, and they were ppl who were coming from western cultures. However, Roland does expresse in the video that he is a multiculturalist who has marxist ideas about wealth creation so I assume such differences do not get registered by him as anything meaningful, so maybe I shouldn't make too much about his rational on that front.
