I've never seen LSEs as ethical conformists,

They (LSE) are not conformist; they pride themselves on doing what they want. Period.

Yes, ESTPs and ESTJs are both non conformists, but they express/approach that it in different angles (Hence, quasi-identical):

ESTPs are more rebellious, you-can't-stop-me-motha-fucka from chasin my dreams, erratic type of non-conformity.
ESTJs are more traditional, its my-way-or-the-high way, anal but reasonable type of non-conformity.

I believe people characterize the ESTJ type as conformist because they do want to appear as "normal" as possible according to societal standards. Whereas with ESTP, not really, hence the going after big dreams thing.
