MM ... There´s normally nothing too outrageous though the leathermen float is very risqué ... There´s always this one guy that marches naked with his body painted in the colours of the Republican movement .
As far as a heterosexual parade is concerned ´.. it wouldn´t be boring ... just different . Like Carnival in Rio de Janeiro .
I always remember the quote " Being straight isn´t normal , it´s just common . " Jejejejeje .
I agree with MM , Teachertraveler8 , you will not see protesters at the march . Millions will be on the streets ( not necessarily in support of gay rights ) but enjoying the party .
Spain does have it´s homophobic side but you rarely see it , even on a normal day .
