I did say "unlikely" which is to say it's not impossible to find homophobic behaviour in Soho. Indeed lets not forget that one of the most monstrous gay hate crimes of recent times, the bombing of the Admiral Duncan pub took place in Soho. This was as you say, by some one who purposely came to Soho because of the reputation of the place, to perpetrate it. But generally Soho is one of the most gay friendly places on the planet.
