Asylum Seekers Having to Undergo "Arousal Tests"

I was hoping I had read enough horrible things for one day after posting the previous post not even an hour ago, but I was clearly wrong.

BBC reports that asylum seekers in the Czech Republic have had to undergo 'arousal tests' to determine whether or not they are truly gay, since being homosexual is a valid ground for seeking asylum. This is due to the appalling conditions that a lot of gay people face in their home countries, including violence, rape and persecution.

How this clear violation of human rights and integrity should be regarded as anything less than the persecution a lot of these men have to undergo in their home countries is unclear to me. The article reports that the men are made to watch heterosexual porn, and if they become aroused while watching, they are denied asylum. There is nothing to say that a man cannot get an erection from watching porn even if the actors are heterosexual. Besides, how is one tested if one is a bisexual male? As a bisexual male, having a relationship with a male is still going to make people do all sorts of atrocious things to you in the countries where homosexuality is illegal or completely unacceptable culturally.

Regardless of whether the test works or not, no one should have to go through sexual tests of any kind in order to determine whether or not someone should be granted asylum. According to the same logic, trafficked men and women should be ordered to perform certain sexual favours to prove that they are sex workers. (I know that being a sex worker, especially one held under coercion, doesn't automatically teaches you sex tricks, but it is a common misconception.) It is completely unacceptable, regardless of existing written consent. Come on, what are the asylum seekers going to do? Refuse to undergo the test and be sent back with all certainty? It is a ridiculous defence and would not hold anywhere.

This whole ordeal also strikes me as very unequal. Or perhaps they have thought of ways of testing lesbian women that I have not. I shudder at the sheer thought. Is this another one of those cases where male homosexuality is regarded at least doubly as 'awful' as women's? In either case, it is appalling.
Shame on you, Czech Republic!
