::In any other environment and given the choice of all words thus far considered, "vulgar" would be (IMHO) stipulated by all sides as precisly the right word to characterize the subject-at-hand.  In the sourcing that has thus far been examined, where the source actually elects to characterize the subject, "vulgar" appears to be the word of choice. 
 ::And what of "homophobic"? Is this a characterization so dominant that it actually warrants "widely regarded as homophobic" warranting zero expression of what might be considered an opposing view? Are the sources for "homophobic" expressing the source's view or predominantly parroting that of the proponent's view? And where are the voices of the WP:NPOV acolytes inre "homophobic? Cue crickets.
