'I actually worry a lot that as I get "popular" I'll be able to get away with saying stupider stuff than I would have dared say before. This sort of thing happens to a lot of people, and I would really like to avoid it'

Edit: the essay itself seems... not very perceptive. Notably, putting things on a continuum between far left and far right and imagining that everything is somehow a process of picking out options on this continuum seems amazingly reductive.
Further, the dig on "intentional moderates" also seems to miss the point that many intentional moderates might well be seeking to function politically - so picking out moderate positions in the range of public opinion might be a case of keeping your powder dry and being effective, not compulsively trying to be a moderate because it's nifty. This was very much the case with the way Obama analyzed his own politics (turning the huge ship, very slowly). Not saying I agree with that but the assessment of "intentional moderates" really feels like a cartoon.
