Britian at the world cup in Russia

The UK government has warned the millions of "British" LGBT's travelling to Russia for the world cup next week that they can't be guaranteed their safety, how can it? why is it expected in a foreign country? they can't guarantee safety in the UK, people get killed every day and the Russians are not supportive of the LGBT's etc like the UK is, I don't think anywhere in the world encourages them as much as the UK, yes Spain has a lot of gay men, but not many of the gender confused and undecided genders etc, so they should be careful when abroad and not rely on help from the authorities like they do in the UK
