Wow, that's quite a load of crap. There are many, many factors that go into a party affiliation - feelings about government, economy, social issues, fiscal issues, international policy - and on and on. On each of those issues people within a party fall somewhere on a spectrum - some may be far apart from one another on any given issue yet still belong to the same party. So I do think it is pretty lazy to generalize about Republicans about specific issues - especially when you are basically saying that all Republicans are racists. That is ridiculous.
You may be able to generalize by party at a very high level on certain issues - like republicans are generally fiscally conservative, believing in smaller, less intrusive government - stuff like that. But saying Republicans "like Asians as a backdoor way to hate blacks" is over the line ridiculous.
