I don't get the concerns of many that the conservative establishment are using borderline White Nationalist talking points to attack their political enemies and win popular support - this is an objectively good thing, it is surrendering to us the moral/ideological high ground.

The idea that it will delude our movement into unduly trusting the conservative establishment is manifestly untrue. Our ideological radicalism on the issues which matter most is only increasing and our criticism of populist figureheads is as sharp as ever - the more concessions we get, the more demanding (not less) we are becoming.
