Chris Brown just lied through his teeth ... tweeting that he has "total respect for [the] Gay community" after dropping another gay slur in L.A. yesterday.

Listen to the way he hurls the word around -- Chris clearly used the word "gay" as an insult ... no two ways around it.

Still, we still gotta ask ...
