Perhaps they were disturbed about a Polish woman and a person from a third world country. There are bigots everywhere.
I Cannot blame them, since Europe is being invaded right now.

That is a good question.
While Homossexuality can be a way to fight against Islam as much as Bacon and Vodka, on the other side the Leftwing use the Homossexuals to their own evil purposes (and usually after size power, this same Left Wing execute those homossexuals that supported them, like Fidel Castro and Robert Mugabe done).
That is why Pim Fortuyn, famous dutch writer, philosopher and politician (and also gay) once said:
"There is nothing more stupid and incoherent than a Left-Wing homossexual"
