I think Spencer has also got some neurotic obsession about status that is shared by his cronies. The reason he and his ideas failed is because they are low status, and hence conservatives are low status-the best way to get in good with high status people(upper middle class striver White liberals), is to bash conservatives, to do this is Eugenic because liberals will have White kids and this will lead to Apollonianism…for reasons.
You’ll notice he never talks about Jews or blacks, even indirectly. At least in public. Because it’s low status, it has a connotation of Cletus with his teeth missing shouting about niggers.
And if there is anything Richard doesn’t want to be known as-as White trash, low status. Combine this with a Nietzchean larping and his own ego, and you get current Spencer.
As for the race realism-of course it’s own uncomfortable. Every White person has been suffused to the bone with the notion that races are not in fact equal and Jews might be a problem is so outside the pale it may make you physically ill, or very uneasy. It’s a complete overturning of the fundamental things we accept in the modern west.
Spencer might make an argument that this is a low status thing to say-higher status people will not speak or engage in ideas that are so threatening and upsetting, and in doing so remove themselves from notable circles. Or something alone those lines. But this is false, and it’s pointless. You’re never going to make any change until you get over the massive consequences of the word “racist” used to police Whites.
But that wouldn’t ingratiate liberals so it’s currently fashionable.
TLDR: Spencer is obsessed with status, acceptance of what he deems as high status peers, and believes he is owed deference.
