as though
or
as if
are better grammatical choices for your use of "like"

Doesn't good grammar mandate that sentences start with an upper case letter and end with a period? Plus, where are the quotation marks around the phrases you suggest the subject of your criticism use en lieu of "like"?

i do not advertise myself as "the grammarian" as the addressee of my post does

i merely point out the irony

Perhaps you meant to use "in lieu" (lieu is a foreign word that has been adopted in the english language and thus there is no need to italicize).

If not perhaps you thought "en lieu" was a foreign phrase and therefore it would need to be italicized.

Grammar gotcha is a silly game to play on a thread site. That is why I pointed out the self-proclaimed grammarian's less than best word choice - and mind you I did not write that he was wrong - I noted instead that better word choices exist.
