I don't know how easy it is to abuse a system whereby if you want to claim asylum you need to prove you are gay in an interview... It was only as recently as 10 years ago where applicants were literally submitting their own photos and videos to try to prove their sexuality. While this has since been stopped (by Theresa May of all people), I can't imagine that such a interview process is much less difficult to manipulate or harrowing for an an asylum seeker.
Also the statement that "The UK cannot be the refugee camp for the entire world" is so bafflingly ignorant and flippant that I can barely believe it. Deciding to focus on some of the most marginalized and vulnerable people is revolting.
